So I have been running a 32 gallon biocube for about a year which has been fairly successful. I had a long and difficult battle with dinos for a few months which I eventually won. I knew that the reason I had the dinos was bottoming out of my nitrates and phosphates which had both reached 0.00. So fast forward to now the tank is looking better and clearer than ever and I couldn't be happier. Just to go over my livestock I have a clown, royal gramma, midas blenny and about a dozen snails, no corals yet. In order to avoid another dino outbreak I have stripped back my filtration to pretty much nothing, no skimmer, no bio or chemical media, just filter floss and a 15% water change every two weeks and the tank looks great. The only thing is even with the complete lack of filtration I have still been getting 0.00 nitrate readings for the last month or so. My phosphates have been consistently good at 0.02-0.05 but the lack of nitrates has me a bit worried about another possible dino outbreak and I just dont know what else I can do since I have already stripped all the filtration. All input is appreciated, thank you guys.
