Aquarium Care

What is the first thought which comes up to your mind when you hear about jellyfish. Yes, it is certainly something quite mysterious since the jellyfish are announced to be one of the most enigmatic creatures in seas and oceans. Actually, the first information about the jellyfish’ existence is more than 4000 years old but just 50 years ago, we hardly knew anything about these creatures. Perhaps, if you are over the age of 30 you remember that it was only possible to see jellyfish in the big and public aquariums. They used to be one of the biggest attractions, actually! But nowadays, jellyfish could easily become your new pet! It is great, isn’t it?

But nowadays, it is very easy to purchase a jellyfish and look after it in your own aquarium. What a sudden change? How could things have altered for 50 years? Could the jellyfish have evolved? Hmm, it is definitely not a good guess since evolution is a process which takes millions of years, not a couple of years! The answer is somewhere else.

The truth is that we are already able to have “jellyfish pets” thanks to the great scientific progress. We already know what the jellyfish eat, what temperature of the water they like, even how they “give birth”. So, it is not surprising that looking after a jellyfish is already effortless and absolutely possible. You could even take care of several jellyfish pets depending on the size of your aquarium- it is your only limit!

Yes, you read it right: pets! It used to be the snakes some time ago and now it is the jellyfish. The surveys show that the number of people purchasing jellyfish as pets is increasing steadily! Perhaps, it is a fad…or not! Only the time will show us. But whatever it is, it seems like the jellyfish will soon become an obsession for many people.

The conclusion is that if you like to experiment, you should not think twice before going to the pet-shop and purchasing a couple of these wonderful maritime creatures. But if you like to think every next step through, you might need some more time to decide. However, I will try to help you by saying that looking after pets like jellyfishes is much cheaper than you probably need. All you need to do is give them food and keep the levels of oxygen favorable. And the best thing is that it is exactly as easy as it sounds! There is really nothing you have to worry about. Furthermore, you can always return the pets if you think that you cannot handle with such a “responsible task”. However, I am sure you won’t want to do it since looking after a jellyfish will not take more than 10 minutes of your day!

Jellyfish are easy to keep as pets today due to new technologies and information. It’s easier then you may think. Start yourself off with the Moon Jellyfish. Visit our website to learn more about setting up a Jellyfish Aquarium.

Aquarium canister filters are needed in order to maintain the balance and cleanliness of the aquarium. This type of canister filters may be used for either a freshwater or saltwater aquarium. Depending on the type of canister filter, it may contain media that may filter the water through mechanical, chemical, or biological means.

When you look at the built and functions of the canister filter, these are quite similar to that of the ?hang on? filters. However, the canister filters are designed to provide more mechanical filtration compared with that of other filters. These filters are best used for aquaria that have fish types that tend to be messy eaters. Unlike most filters that are hung on the tank, canister filters are usually placed below the tank. At times, you might also find them inside the tank. For this type, the term ?submersible filter? is used. Some aquarium owners also choose to attach a wet-dry wheel to the outflow of the canister filter, which leads to the improvement of the biological filtration.

Most canister filters are designed to filter larger amounts of water compared with conventional water filters. These are also easily customized that you can specify if you would like the canister filter to have a mechanical, chemical, and biological functions. You may also ask for a canister filter that has bio wheels, UV sterilizers, or a water chiller.

The most noteworthy disadvantage of having a canister filter is the need to clean it frequently. Because this functions mainly as a mechanical filter, the debris from the water can easily clog it up. If you decide to submerge the water filter, clean up will get even more tedious than if the filter is located outside the aquarium. Despite the trouble in cleaning the filter, you have to do this often to prevent the decaying and toxic waste from coming back into the aquarium’s water.

Once the water has been freed from the chemicals, it is allowed to pass through the bacteria bed, wherein the bacteria present in the bed change the nitrites into nitrates. This biological filtration is necessary in order to lessen the toxic effects of these chemicals.

Guide to proper choice of canister filters

1. Replacement parts are readily available

When shopping for a canister filter, you have to inquire if the store also carries replacement parts for the filter. Although the filter is durable and is guaranteed to last for a long time, there will be a time that you will have to change the parts of the canister filter as part of maintenance. It is best if you have spare o-rings, impellers, and rubber gaskets. You can?t be sure when you will need to replace them.

2. Are these the right ones for your aquarium type?

Just a short reminder: Although canister filters work with both freshwater and saltwater aquariums, there are some that work only with freshwater aquariums. Be sure to inform the seller if you will use it with a saltwater aquarium.

3. Ease of installation and use

At first, an aquarium expert can help you with installing the filters. However, after this, you are on your own. Choose a canister filter that is easy to maintain and replace, even by a non-technical person. There are lots of advantages in getting a canister filter for your aquarium. Just keep these simple tips in mind when getting one so that you maintain the balance in your aquarium?s ecosystem.

I was first introduced to the concept of pH back in high school chemistry when we dipped little blue and pink strips of paper that changed color depending on the acidity or alkalinity of the solution. Of course, all I had to do was remember the acronym B-R-A, meaning “blue to red - acidic” to pass the subject. I didn’t foresee that I’d have to deal with the pH phenomenon for the rest of my life. Now that you’re hooked on the hobby, you will have to deal with it, too.

Let’s start with what exactly pH is and then we’ll elaborate on its role in the aquarium and why you need to know how to manage it.

Basic Concepts

pH is short for “pondus hydrogenii” meaning “potential hydrogen,” “power of hydrogen,” “weight of hydrogen,” and “predominance of hydrogen ions (H+)” as a measure of the acidity or alkalinity of a particular solution.

The pH scale is expressed as the negative logarithm of the hydrogen ion concentration ranging from 0 [high concentration of hydronium ions (H+) = acidic] to 14 [high concentration of hydroxide ions (OH-) = alkaline/basic]. The pH concept was introduced by a Danish chemist, Soren Sorensen, in 1909 (if logarithmic formulas and chemical equations will help you better understand how the pH scale was devised, and how it is applied, the site on Sorensen would be an excellent resource).

Factors That Affect pH

Pure water has a pH value of 7 which is considered neutral (neither acidic nor basic), and generally the ideal condition for freshwater aquaria. However, various factors can cause the water parameters to swing several notches towards acidic or alkaline, which, although almost negligible, could be fatal to the fishes. Here are some examples:

1. Water Source – normally, tap water would be within the neutral pH range but some water sources are naturally “soft” or “hard,” or chemically treated such that the pH level diverts from neutral.
2. Substrate and Decor – your choice of substrate and decorative items will influence your tank’s pH reading over an extended period of time. At first, a substrate spiked with corals, shells, or limestone deposits will show high pH levels (influenced by the hardness or mineral content of the water), which could later on diminish as the minerals are used up. On the other hand, the presence of peat, or driftwood that leach tannins, can swing the scales towards the acidic side.
3. Maturity of the Tank — the natural tendency for well-established tanks is to dip towards acidic. Fishes eventually adjust to this trend, but not if it falls into ranges that are already toxic to them.
4. Plants — taking an active role in the nitrification process, plants help to maintain a relatively neutral pH by absorbing dissolved salts and waste products.
5. Water Circulation and Aeration — without adequate aeration, carbon dioxide can remain trapped in the water and lower the pH (make the environment acidic).
6. Overstocking, Overfeeding, Excess Medication, Poor Filtration — in short, inefficient tank maintenance can wreak havoc on your pH levels.

pH and You

Every well-meaning aquarist needs to have a pH test kit handy. Various types of kits are commercially available — they’re mostly inexpensive but will be a valuable tool in your efforts to maintain the ideal home for your pets.

Test your tap water to make sure it’s safe for the types of fishes you’ve chosen to keep. Remember to pre-check the parameters of the new water you bring in when you make water changes.
Test your aquarium water regularly (daily when setting up a new tank; once or twice a week for established tanks).

Consult your local fish store for the availability of buffer solutions in case you need to make drastic adjustments in your pH levels.

Add an EcoBio-Block to your tank. Its resident beneficial bacteria help control the conditions that can cause unhealthy changes to your pH level.
