Powerful and silent

I had 4 Koralia 4 controllable pumps on my Wavemaker 4. They did not push enough water for my 150 gallon reef tank, which has a large amount of SPS. I decided to upgrade two of them to Koralia 7's. Be certain you are ordering the 12V versions for your wavemaker. Read the descriptions carefully to distinguish 12V from 120V model. The Koralia 7's installed as a direct replacement for the 4's. They are larger but not that obtrusive. The main difference I noted was the screen/flow director in the front is not removable on the 7's. This is helpful as the old units required a dab of superglue to get the end to stay on securely and not fly off from vibration. The second advantage is the quietness at startup. The 4's would rattle for a second whereas the 7's are silent. Don't let the quietness fool you. The 7's push massive amounts of water. In fact, I had to go into the program section of the Wavemaker and turn the max rpms down so that my fish were not tossed around. Thankfully, the Wavemaker allows this. The second change was where to direct the jets. With the 4's, it was not much of an issue and the circulation petered out at about 3 feet from the pump. With the 7's, there is a strong flow across all 6 feet of the tank. That can be used to make some interesting turbulence patterns. After some experimentation with the Wavemaker programs and the positioning, I found a reasonable random turbulent flow over my SPS. The fish are still getting used to higher flow. I will probably invest in the photocell to turn down the flow at night. All in all, these pumps are an impressive product that move a huge volume of water and are energy efficient.
