Why Aquarium Water Testing is Important

One important thing that a person setting up an aquarium must not overlook is aquarium water testing. When you have arranged the decor in your aquarium and put water in, do not immediately add the fish but instead, let the water stand for several days to let the water settle. Beneficial bacteria in a product like EcoBio-Block will help you to speed up the nitrogen cycle. You can monitor this cycle daily with water quality tests, and add the fish a few at a time. At the start of the cycle, you will see a spike in the ammonia level. This will be followed by a nitrite spike when the beneficial bacteria convert the ammonia into nitrites.

Once you have fish living in your aquarium, test the water daily for the first few weeks as the water adjusts to having fish living in it. After this initial period, test the aquarium water weekly. Although most aquarium supply stores will test it for you, it is much easier to purchase a water test kit and do it yourself at home.

You will be presented at the aquarium supply store with a wide variety of testing kits to choose from. There are basic kits with strips that test important water quality indicators like pH, nitrate, water hardness, ammonia, nitrites and others. The strips change color to indicate the quality of the water.

The basic kits are convenient, but have some drawbacks. They are cheaper but are not very reliable. You can go instead with more complex testing, which involves a test tube. Add also a thermometer to your testing supplies so you can test the water temperature.

The health of your fish depends largely on the quality of the aquarium water. That is why it is essential that you do regular aquarium water testing. You need to add whatever is necessary in order to bring your water level to healthy levels for your fish.

Healthy pH level is around 6 or 7 for most fish, but they will generally tolerate a fairly wide range of pH. Any decor, food or medication added can change the pH level in your aquarium. You can increase or reduce the pH to healthier levels by adding some chemicals. A natural, but much slower approach will be to add driftwood or peat for more acidic water or a lime rock if you want more alkaline.

High ammonia levels are toxic to fish. Nitrite levels too, must be kept as close to zero as possible. What will reduce both will be partial changes of water. An easier way is to add beneficial bacteria. Nitrites will be converted to the less harmful nitrates by the beneficial bacteria.

Even simpler and less trouble is to have a bacteria colony established with the EcoBio-Block which gives long-term, continuous results. The bacteria breaks down ammonia into nitrites and then into safer nitrates. The bacteria live and multiply in the block and disperse into the water, keeping the water clear and healthy.

Aquarium water testing is a very important part of keeping your aquarium environment safe and healthy for your fish.

How to Safely Add New Fish to an Established Aquarium

Introducing new fish to an already existing aquarium is not as easy as it may seem. There are a lot of things to think about and prepare before you can safely transfer your new fish to your aquarium. You cannot just buy any aquarium fish you want then dump them in the tank as soon as you reach home.

First thing to check is the quality of your water. It is stressful enough for all the fish involved when new fish are introduced to their number. Do not add to it by making them suffer in poor water quality. The stress in them might reach fatal levels. Make sure that you have the highest possible water quality by testing for the ammonia, nitrite and nitrate levels. Do the necessary changes or cleaning before you add the new fish to the aquarium. If you dont like frequent aquarium cleaning, add an EcoBio-Block to your aquarium to give it the beneficial bacteria and trace minerals that can reduce harmful substances in your water and keep it clean, healthy and clear.

When choosing what fish to add to your aquarium, you need to determine if they will live companionably with your existing fish. Some fish will eat smaller fish, some others will fight and kill each other. You also have to know if your water will sustain the new fish. This means that you have to get the aquarium fish that will survive the temperature, pH, nitrate and ammonia levels you currently maintain. It is advisable that you add more than one fish at a time, to reduce the chance of any fish picking on just one new fish.

Your first step when preparing the aquarium for a new arrival is to rearrange the tank. Your established fish have their own hiding spots, and may become territorial if a new fish is introduced. Rearrange the plants and decorations, which will remove established territories and make the environment new for all of your fish. Make sure that there are plenty of hiding spaces where the fish can go until they get used to each other.

When introducing new aquarium fish to an established tank, never bring your new fish home from the pet store and immediately dump them into the tank. This will shock their system, and they may not make it.

For best results, you may want to set up a separate tank where you quarantine new fish for a week to check for signs of illness. Sometimes, pet store fish carry diseases, and you don’t want to introduce these into your aquarium. If you decide to transfer your new fish directly from the pet store bag to your established tank, first float the bag with the fish in your aquarium for a few hours. This allows time for the water temperatures to equalize. Then, open the bag to release your new fish into the tank.

Careful preparation to the aquarium, timing of the introduction of new fish, plus proper acclimatizing will ensure a smooth transition with minimal stress to all your aquarium fish.

Aquarium Care Series: Treating Common Ailments

by Ruby Bayan, OurSimpleJoys.com

Prevention is always better than cure, so making sure that the aquarium environment is always ideal is your best preventive measure against illnesses. This means regular check-ups on the optimum efficiency of the equipment, constant monitoring of the integrity of the water condition and temperature, diligent precautions against introducing harmful elements into the environment, and most importantly, a close eye on the fishes themselves. Keeping informed on the latest innovations in water conditioning for fish health is also important; for example, beneficial bacteria found in products like EcoBio-Block could help prevent infections and disease.

However, sometimes, no matter how cautious or diligent you are at ensuring the health of your fishes, untoward circumstances bring about health problems that need serious attention. If only for this unpredictable occurrence of fish ailments, you should be ready with enough know-how on ways to address fish health problems.

Bacterial and Fungal Infections

The most common health problem among aquarium fish is infection from bacteria and fungus. The primary culprit is usually bad water quality. Pollution due to the rotting of uneaten food, irregular water changes, and poor tank maintenance contribute to the deterioration of the habitat — this makes the fishes weak and susceptible to infections.

Stress, from mishandling, introduction of aggressive or incompatible species, and habitat disturbances, also leave the fishes traumatized and susceptible to diseases. Malnutrition, or an inappropriate diet, aggravates the situation – anything considered malnourished is definitely taking a serious health risk.

Here are some examples of bacterial and fungal infections, and how to deal with them:

  • Fin Rot – Fish with long, trailing fins are most susceptible to fin rot – a degeneration and inflammation of the fin rays and membranes. Aside from poor water quality and vitamin deficiency, fin rot is often the result of infections arising from damage brought about by mishandling, as well as fin-nipping attacks from tank mates. Infected fish should be removed and the affected areas treated with commercially available anti-bacterial fish medicine. Remedy water condition and compatibility problems, as well as diet deficiencies to prevent the spread of the ailment.
  • Fungus – Aside from bacteria, fungus can attack the areas on the fish body that has suffered some extent of damage (such as wounds or holes left by parasites). Cotton-like fungal growth appears as patches that give the fish a dull, shabby appearance. To treat fungal infections, subject the tank to a fungicide remedy. Address other possible causes like poor water quality, parasites, and aggressive tank mates.
  • Pop-Eye – One of the more serious bacterial infections is called pop-eye, marked by inflamed eyes protruding from the sockets. Looking very sickly, fish infected with pop-eye usually contract the ailment because of poor water quality, mishandling or distress from fighting with other fishes. Antibiotics may be effective but, if the infection has progressed to a form of tuberculosis, the afflicted fish may have to be removed and euthanized.

Parasites

On rare occasions, even the most cautious aquarist can unknowingly introduce parasites into a well-maintained tank. New fishes, live food, live plants, and some decorations are all potential carriers of aquatic parasites. Here are some of the parasites you should watch for:

  • Fish Lice – Also known as Argulus, fish lice, looking like transparent flat disks, attach themselves to the skin and suck on the fish’s blood. The fish feels itchy and scratches itself on the substrate or on rocks and other hard décor.
  • Anchor Worm – Lernaea, or anchor worms, are greenish-white threadlike organisms that attach themselves to the body of the fish. The skin becomes inflamed and the fish scratches the affected area on hard surfaces in the tank.
  • Leeches – Worm-like leeches attach themselves to the host fish to feed on its blood. The fish feels the irritating suckers and tries to scratch them off on the substrate, rocks, or wood.

To treat parasite infestations, remove the afflicted fish from the tank, and with a pair of tweezers, pull the parasites off. Apply antiseptic to the wounds. Proprietary treatments against specific parasites are commercially available. You will have to treat the whole tank to prevent further proliferation of these harmful organisms.

Other Ailments

Aside from attacks by bacterial, fungus, and parasites, fish also suffer from other maladies, mostly related to intestinal or organ problems. For example:

  • Dropsy – Characterized by a severely swollen or bloated abdomen and is believed to be caused primarily by poor water quality (high nitrate or sodium chloride levels) and malnutrition. Remedy, therefore, involves correcting the habitat conditions and the fish diet.
  • Constipation – Sometimes the fish fails to digest food properly due to a poor diet and overfeeding. Constipated and bloated, the afflicted fish will not want to eat; hardly discharging feces, and feeling weak, it will often rest on the substrate. Experts suggest adding a teaspoon of Epsom salts to every 10 liters (2 gallons) of tank water, and then making sure that the fish is fed the right food in proper quantities.
  • Swim Bladder Disease – Poor water quality, mishandling, and congenital disorder are the main causes of swim bladder disease. The afflicted fish has difficulty staying upright, oftentimes swimming upside down or sideways. Antibiotics and improvement of the water conditions can correct bacterial infection due to a poor habitat. Congenital disorders and permanent swim bladder damage, however, may be irreparable, therefore, euthanasia should be considered.

How to Cycle an Aquarium

aquariumcycleDid you ever think you couldn’t have fish because “they just die”? If all your fish die within a week of buying them, it’s not just the fish. The most common cause of mass fish deaths is an improperly cycled tank. Before you buy any fish, it’s absolutely imperative to make sure your aquarium is well-cycled.

What is cycling? Simply put, the cycling process is the time it takes to set up a biological filter for the nitrogen cycle to function inside the aquarium. Your aquarium is much more than a tank full of water, it has to be an entire contained eco-system to keep your fish healthy. The goal with your cycling time is to develop a culture of beneficial bacteria (or “bio-bugs”) that will break down the ammonia from the fish’s waste into nitrites, and then from nitrites into nitrates. Ammonia is extremely toxic to your fish and will kill them very quickly with much less than one part per million in your aquarium.

There are several methods for cycling. This is a method that is very effective, easy to do even for beginners and does not subject any live creatures to the potentially deadly cycling process. First, set up your aquarium with filtration, heater, aerator, etc. and fill with water. Add whatever de-chlorinator you prefer; if you’re not sure what’s in your water be sure you use a treatment that eliminates or neutralizes chlorine, chloramines and potentially harmful metals. With the filter running, add a tiny amount of fish food…about one or two flakes. The food can be old, stale food that’s no good for feeding anymore — it’s only there to rot. As the food decomposes it will produce the ammonia that will feed the bio-bugs as they get established in your aquarium.

That’s it! Keep adding one or two flakes every day throughout the cycling process, then do a partial water change before you add fish. It’s safe to add fish when both ammonia and nitrites test at zero but there are nitrates in the tank to show that ammonia is actually being broken down. A full cycle takes 36 days to complete, though some hardier fish can be added after a couple of weeks as long as you keep a close eye on the water parameters.

Don’t want to wait 36 days? There are a few products on the market that can help speed up the process. There are bottled, refrigerated products such as Bio-Spira that can give the cycle a big boost by adding the bio-bugs directly (via a liquid) instead of having to wait for them to get established in the aquarium. The only problem I’ve found with those products is that you add them, it boosts the bacteria, and that’s the end of its use. One great cycle-time reducer is the EcoBio-Block. This product is a little more expensive than Bio-Spira, but you get a lot better value for your money.

To use the EcoBio-Block, rinse it off in some de-chlorinated water and then place it in the tank after the water has been treated and filtration is going. Make sure you set it somewhere near the aerator or below the flow of an HOB filter (the kind that hang on the back of your aquarium). The EcoBio-Block has the beneficial bacteria the aquarium needs sealed into it; the flow of water facilitates the dissolving of the seal and ensures that the bio-bugs get the oxygen they need. These blocks can take a couple of weeks to start working (though sometimes they work much faster), and once it’s working you’ll be able to begin adding the fish you want, hardy or not, because this effectively finishes the cycle. Test your water; it may not be necessary to do a partial water change before adding fish unless there’s an excess of decomposed fish food in the bottom. Don’t take the block out! The EcoBio-Block is still useful for about 1 1/2 to 2 years; it’ll keep the bio-bug population healthy and contains all the trace minerals that normally have to be replenished through water changes. The minerals are time-released into the water to keep it healthy without constant water changes.

In short, the cycling process is simple but time-consuming. If you decide to shorten the cycle time take care with which product you purchase to help, there are a lot on the market that don’t actually do what you need. The above have proven to be good, reliable products that greatly aid with this process. Once you’ve achieved a good biological filter and the nitrogen cycle is up and running, you can start adding the fish!

Aquarium Care Series: Aquarium Hazards

by Ruby Bayan, OurSimpleJoys.com


Many years ago, I got involved in an aquarium decoration contest, where my winning entry was a tall 100-gallon tank that featured a fully set-up 5-gallon tank inside it. I can’t remember what fishes I put in there but I won the gold ribbon. I was proud of my ingenuity.

I often stretch my creativity when I decorate tanks for myself and others, but there are certain limitations and basic guidelines I work with, to ensure that my originality and ingenuity don’t become hazardous to the living creatures I have in my tank.

Pollutants

Water is the universal solvent, and anything that dissolves in water has the potential to pollute your tank environment. Therefore, the following water-soluble materials should never come in contact with the water in your aquarium:

  • Paper-based items
  • Textile or fabric
  • People food

In case of minor pollution accidents, and to minimize the hazardous effects of cloudy and contaminated water, consider adding water-conditioning products like EcoBio-Block, which uses beneficial bacteria to clarify and deodorize the habitat.

Toxic Materials

Chemicals dissolved in water can render your fishes ill in minutes. At high concentrations, toxic materials can kill them in seconds. Exposure to metallic substances that can contaminate the water, even in negligible quantities, can eventually stress the environment and make your pets susceptible to disease.

Here are some of the potentially toxic materials that you should keep away from your tank:

  • Metallic objects or toys, figurines, and knick-knacks that contain exposed metals
  • Dyed items that leach when wet
  • Oily items like crayons, modeling clay
  • Items that have come in contact with household chemicals like detergents, pesticides, cleaners, and solvent

Natural but Hazardous

Most often we are misled by the idea that since a decorative item is natural, it’s safe for the aquarium. Since we are maintaining freshwater aquaria, introducing driftwood, rocks, and shells that we picked up along the way can risk upsetting the “freshwater-ness” of the tank.

The rule of thumb is to refrain from introducing anything natural that may have come from a non-freshwater environment. The risk is that these items may be carrying mineral deposits, microorganisms, and parasites that existed in their natural locations.
Rocks, shells, and corals that may be innovative additions to your aquarium may leach calcium and other minerals that will affect the stability of your water composition. Driftwood can leach tannins that your fish may not be able to tolerate.

Many attractive artificial (hard plastic; inert) alternatives are available, and highly recommended, but if you would rather use natural wonders, here are tips to ensure they are safe to include in your setup:

  1. Wash the décor in clean running water, scrubbing off all loose particles. Do not use detergent. Boil rocks, shells, and corals for an hour or two for added measure. (Hint: Splash some vinegar on the rock/coral and if it sizzles, the item is calcium-rich and is better suited as a decorative accent on your bookshelf.)
  2. Soak the décor in a bucket of clean water for about a week or two and replace the water daily. This will help remove minerals and tannins that could leach in water.
  3. Dry the décor under the sun or in an oven to kill microorganisms and parasites that may still lurk within the item.

Moving and Disturbing

Those nifty action aquarium décor that opens and closes and goes up and down animated by bubbles rising from an air-stone can be quite engaging to onlookers. The pirate treasure chest, the little boy fishing, and the cute pearl clam — they look cute and interesting, but did you notice how they make some fishes nervous?
Eventually, the fish will get used to the animated items, but not before several days of stress and anxiety. By the time they get used to the jerky décor, it’s time to pull it out for a cleaning. Then when you put it back in, the fish will become jittery again. So, use your better judgment when using these supposedly attractive decorations.
