I have purchased 5 30 gal. tanks that are seperated into 3 10 gal. tanks each. I've got a 30 gal. sump with a skimmer and a UV sterilizer on the discharge side of the sump. My question is this- I've always had reef tanks that had to cure out before placing fish into system, so is it necessary to generate this correct balance of algae and microrganisms in a system that is fish only? Also wouldn't the sterilizer kill most of this anyway. I'm in the process of building the sump and need to know if I need to put rock, sand, grunge, and refrigrum in if the sterilizer is going to kill what I develop.Thanks in advance for your help with this.
