Nitrate problems

[ed99]

I've also seen a strong correlation between rinsing (or not rinsing) frozen food and cyano outbreaks. I've been lazy over the last few weeks with the rinsing and the cyano is back.

Bioload sounds at least part of the problem with nitrates here. I had two perculas and two chromises over the summer in 92 gal and I had virtually no nitrates without bothering to do water changes. I've stocked up over the last couple of months (now up to 9 fish) and the skimmer is working way harder.
