hi, what cuc should I add to my 24 nano? just concerned about adding to much of a cuc and them starve. right now I have two fish. a yellow tail damsel and a firefish. no aggression from the yellow tail. anyhow planning on adding a pair of clownfish soon. im planning on using some chemipure elite and purigen on my media basket and running my tunze9002 skimmer with the steve t collection cup. right now still going through the diatom thing and notice some hair algae growing on the 2lb live rock I purchased from the lfs but I just was wondering whether or not to add a cuc ? if so what ? and how many? thanks
