Howdy,
I know this this topic comes up often but I'm battling zero nitrates all of a sudden... My tank for the past 4 months was happily at 10 ppm and all of a sudden some brown diatom slime has been forming on the substrate the last month. I've started to dose alk and ca BRS two part - nothing else has changed. I'm trying to understand why the sudden drop. I stopped doing weekly water changes to help my nitrates remain detectable.
I've thought about dosing sodium nitrate to just keep my nitrates at 5 but fear that I'll throw nitrates way the other way.
I have two clowns two Cardinals and a orchid Dottyback it's a 30 AIO... should I add more fish?
