Ok, so Ammonia and Nitrites have been 0 now for a while, and with Nitrates going up to about 80, I'm starting water changes.
I choked out and killed the cyano and i don't see any other algae on the substrate either, a little on the glass in the back. What I want to know is should I add a CUC even though i don't see really any algae, or should I add a fish then next month put in a cuc? Once I reduce Nitrates.
