Review: Great circulation pump, quiet and effective! - I have a 29g Biocube and I think I've finally settled on this pump to accompany the return pump in the tank. The return by itself does not move enough water around, but with this one added into the setup it seems to keep most of my corals happy. I've had this pump installed for about two months and everything has been going good so far. There are a couple great things about these Hydor Koralia pumps, most notably the price and also the magnets used to attach the pump to your tank wall. It's simple, clean, and easy to move or remove for cleaning. In addition, the pump is very quiet and can barely be heard when running. The only suggestion I would have for this unit is to disperse the water out a bit more as it seems to be pretty directed. Pros: + Lower price than competitors + VERY quiet when in operation + Magnet attachment system Cons: - Concentrated flow where pump is directed, seems like lower GPH as a result Overall this pump gets the job done and is a good bargain for your money. However, when purchasing a Hydor Koralia pump, be sure to get a larger pump than what you THINK you need, simply because the concentrated flow seems to result in a slightly lower GPH than advertised.
Review: You wont hear it - Great product and pump. Has a lot of strength and water flow is wonderful when you use it. Most of all its quiet and you don't hear it. I wish this company made a wavemaker. The size isnt too small for a nano tank making it easy to position. The larger sizes do tend to jump quite a bit in size and weight.

*by T***L on December 28, 2015*

I bought two of these 425 GPH circulation jets for my 40 gallon saltwater cube tank. I found it easy to install the plastic suction cups to the plastic ball on the unit by first placing the suction cup on the tile floor, and then wetting the cup opening and plastic ball with a small amount of saliva (yes gross but it works), and then firmly pushing the ball straight into the plastic suction cup socket. Once in the tank, I placed one unit in the front right side, and the other unit in the back left side to create a clockwise flow. They are placed mid depth, and angled towards the glass. These locations works great for both fish and coral. I also did not press the suction cups on the glass to hold the units in a static location, as the magnets are strong enough to hold the units from the outside of the tank without pushing the suction cup onto the inside of the tank wall. This allows me to move the jets time to time to create varying flows for the fish and corals. One thing to note is that these units, like any motors inside your tank, will add additional heat load to your water. I have a small fan blowing across the top of my tank set on a temperature switch, which increases the evaporation rate and quickly cools the water when the temperature rises above my limits. The fan was 1/20 the cost of any decent chiller unit, much quieter, uses minimal energy and allowed me to use the saved money to buy an ATO to keep the salinity at a constant level, and keep the tank topped off with the additional evaporation load. In summary, the engineering is sound on this circulation jet, and the price is fair. Just be careful installing the suction cup to the plastic ball pivot...
