So I have a 10 gallon reef with an aquaclear filter. and I have a colony polyp, 2 frags of frogspawn with a 2 heads on 1 and 3 heads on the other. I also have a white alveopora flower pot. I haven't seen any real growth in my corals over the 6 months I have had them, but at least they are not shrinking. I don't feed any of them so I want to add cheap little HOB filter for like a 10 gallon and take out all of the media and add some good quality live rock pieces to it and then put copepods in there so that I can get a good population going, while at the same time adding some extra flow. I thought about adding zooplankton, but with only 10 gallons I don't want to kill the water quality I worked so hard to achieve, and plus I don't see how uneaten live copepods would be a bad thing. Is this a good idea?
