I have been fighting low nitrates for a while now. It never gets above 2, but now it's barly 1. I have done more feeding to the 5 fish I have but no increase. I have a 25 gal AIO and all the.other params are good and stable, except for phos. Its usually around 150. But everyone is happy at that level so I don't mess with that. Dont really have an alge problem, spot her and there of short green alge, so thinking of pulling the chaeto out fir a while. It grows like crazy too. Just halfed it 4 weeks ago and its back where it was. So, if I do take.it all out, how do I keep it alive to put back in later if I need to? And any other advice to raise nitrates a bit?
