Is a Koralia Nano 240 to much flow for a BoiCube 14 gallon? I also saw a CP1 Circulation Pump online that looks like it would do the job. The only pump I have is the powerhead that came with it. I recently put a clam, duncans, frogspawn, hammer, sinulaira and some zoos in there. Most of things will go into my 180 after I use Flatworm Exit since they have flatworms. I plan on using it and then still keeping them in the nano for a month or so. I want to make sure all the flatworms are gone.
