I might not have 0 nitrates but I'm using the API kit and it looks like 0 maybe .25. About two weeks ago I had the water tested at my LFS
. Everything came back good just the calcium was low at like 380ppm. I've since raised it to around 460. I have fed the corals with Marine snow (Maybe) I don't remember what the chemical is and I'm not home currently to check. I also add calcium and other chemicals pending what's low or high.
I run a protein skimmer, filter, 35 lbs LR
, chemi-pure, etc. It's a t5 light with moon LEDs. I have xenia, frogspawn, clowns, dottieback, serpent star, mushrooms, green brain, polyps, cleaning crew, and some smaller frags.
I change my filter about every 2 months and I always put in the new one for a week prior to removing the old one. I use Tap water to top off that's treated with Prime. My tap water is good according to the test tube, just has extra chlorine in it but I make sure to let it sit out and treat it for a week or so prior to using it.
