sump setup for cichlids
Hey everyone! I need some help setting up my sump for my 90 gallon peacock tank. I got a used 30 gallon sump for it with just 2 baffles, and I need help with how to filtrate it. Under the second baffle I put a sponge so that is one level of mechanical filtration. I also have a stash of bioballs and dry rock that I could put in the middle section for biological media. Any preference on these?
Also, any other ideas for mechanical filtration? Whatís better/easier, having a filter sock and holder, or doing a DIY sort of thing with sponges? Any suggestions or recommendations?
