Here's the spiel...converted 20L FW tank to SW it has in it no live rock or live sand, just cc over undergravel filter with a tetra tec "wet/dry" hang on power filter and one power head right now. On the advice of a book, I filled the tank, let it set for a few days and then added two damsels to get the whole thing started. The damsels went in about 2 weeks ago and I have yet to see a drastic ammonia spike. Is the low bioload just keeping the cycling VERY slow. Also, now that I've read here the benefits of LR is it a problem to add it slowly over time (don't have budget to buy 15-20lbs all at once)? If I add live rock should I just kill the undergravel? Any help is greatly appreciated. Oh, the 2 fish are yellow tailed damsels and seem to be happy as hell, just eatin 'n swimmin like mad. Almost forgot, what kinda level should I be waiting for with ammonia and should I be testing for total ammonia or just free ammonia?
