So everyone told me the nano Koralia is weak... and I should just get the koralia one. I didnt listen to anyone and I got the nano Koralia. This thing is causing waves in my 14 gallon biocube. I first placed it near the top.. all my corals looked like they were ready to rip off and fly around the tank... I moved it near the bottom and I got a sand storm... So now I have it in the middle and off untill the sand storm calms down.. Its on the right side of the tank opposite side from were pump shoots out. Any ideas. I also bought the flo deflector but have not installed yet I can only imagine the kind of stuff will by flying after that... might hold off.
