4 Stars Nanote
I have a 10g nano reef tank that I have been enjoying for about a year now. I recently added the Koralia Nano to the tank. The amount of flow this little head produces is impressive. It took my corals 2 or 3 days to adjust to the movement because it was such a drastic change in water flow. Now my fish are more lively (they love the current) and my corals are more vibrant. I really like the dynamic it adds to the tank.

The machine itself appears well built and extremely simple. It has a suction cup and magnet that hold the head stationary inside the tank and another suction cup and magnet that goes on the outside of the tank for added adhesion. You plug it in and it circulates water: one speed, no switches, no adjustments.

4 Stars Works Great buy Pricey
I think this is a great product overall. It is the perfect size for a nano tank. I have a 9 gallon nano saltwater tank and it delivers a great multi directional flow. The best part about it is the magnet holder. Suction cups over time don’t work as well and you constantly have to re-adjust them. The only downfall is the price. All powerheads for that matter seem pricey to me for what you get. Overall, I would by this again. Hopefully it has a good long life span.

3 Stars Broke after 1 year
I have 2 of these in my 20-long reef tank. One broke after about a year, the other one is still going. It’s a great product for all the reasons other reviewers have stated. But a 1-year lifespan is pathetic. 5 stars for functionality, 1 star for quality.

5 Stars No noise
Perfect to help circulate fresh water tanks of 65 gal. no noise. very easy to clean! Worth the price for low current.

4 Stars Great powerhead, but there are some concerns about the magnet
I love how this powerhead stays put. It doesn’t slide, and will stay aimed in whatever direction you point it. It does tend to accumulate debris and floating macroalgae, so you should make sure that it gets cleaned often.

There was some concern about the magnet that’s used, and how it’s prone to rusting. Not sure how this affects water chemistry, but here’s a link for those who are interested:

I’ve been using this powerhead for about 5 months now, and have seen the rusting on the magnet, but can’t really tell if it is doing anything to the water.

5 Stars Great product!
I have two of these powerheads in my 10g nano reef tank and I love them. They are literally silent and provide great water movement. The suction cup with magnet design is wonderful. Highly recommended!

5 Stars Awesome circulation pumps!
I have a #1 pump rated 400 gph for a 12-gallon tank which grows red gracillaria for my Tangs to eat. I have a #3 pump rated 800 gph in my 90 gallon FOWLR tank and my Tangs love it! The produced current is strong and produces wonderful waves. This pump is easy to install onto acrylic or glass - simply use the heavy duty magnet. Highly recommended to add circulation to your aquarium.

Cloudy Aquarium

Many a new aquarium owner has panicked when their tank has taken on the appearance of what one such owner described to me as “a smoke filled room at a party.” In aquarium lexicon, we call such smoky appearance “cloudiness” because of its resemblance to the wispy clouds that sometimes appear in the sky. Everyone who keeps fish as a hobby wants their tank or tanks to be sparkling clean and clear at all times. Cloudy fish tanks look unsightly, and the water in these tanks can seriously harm the health of your fish. What causes these cloudy fish tanks, and what is the best way to get rid of the cloudiness?

The water clarity in a fish tank is generally affected by several factors, and the color of the water can often be a clue as to what is causing it to be cloudy. The water in a fish tank that has just been set up will often display a gray or white tint. This is called a “bacterial bloom” and it is very common in new tanks, for the nutrients and the bacteria in the water are imbalanced.

If your tank is so new that you have not added fish to it, dust from one or more of the decorations you added, or from the gravel or other substrate you placed at the bottom of the tank may be the cause of the cloudiness you see. Any item that goes into your fish tank must be made for that purpose, and you must rinse it well beforehand. When bacterial bloom appears in a fish tank that has already been established, your tank filter may not be working properly. You may be overfeeding your fish, or you may have too many fish in too small an aquarium.

A green cloudiness in your tank water means you are dealing with a sudden algae bloom. There are several reasons for an algae bloom some of which mimic the causes of a bacterial bloom. For example, when there is too much waste matter in your tank, be it left over food or the waste products from your fish, the bacteria from this waste converts into nitrates. As these nitrates grow in number, an algae bloom is imminent. Leaving the tank light on too many hours a day encourages the growth of green algae, and so does a high phosphate level in the tank water.

You may sometimes see a yellow color in your cloudy fish tanks. Decorative driftwood, decayed plant matter from aquarium plantings, fish waste, and dissolved organic carbons, often called DOC, can all be the cause of yellow cloudy water. Occasionally, you may also see a brown cloudiness in your tank water. This is caused from an overgrowth of brown algae. Brown algae can be caused by the tank not getting enough light, or from certain types of driftwood that have been placed in the tank.

By eliminating the causes of the different varieties of cloudy tank water, you can make caring for your aquarium much easier. Partial water changes of 10 to 20 percent of the water can help, as can making sure the filter on your tank is of the proper size. In order to remove the cloudiness from the water, and to make sure it does not come back, you need to see to it that your tank has a good supply of beneficial bacteria. This point confuses many newcomers to the aquarium hobby. They are so sure that bacteria are a bad thing that they balk when told it is needed in their tank! However, once they understand about good vs. bad bacteria, they are eager to know what they can do in order to maintain a colony of the good bacteria. Fortunately, there are some good solutions available. One of the best for cloudy water is the EcoBio-Block. When hobbyists learn of the advantages that go along with placing a product from EcoBio-Block in their aquarium, they agree that this is the easiest solution to the problem.

These products contain live beneficial bacteria, which multiply and make their way into the tank water every 30 minutes or so. They work in new set-ups as well as established aquariums to establish a nitrifying bacteria colony. This will take care of most cloudy water naturally, cuts down on the need for water changes and vacuuming the gravel or substrate, and will last for years. You could almost say that EcoBio-Block products are an aquarium owner’s best friend!
