I've had my Dino's in check for maybe two months or more now. The dirty method was very successful for me (never was able to ID mine unfortunately). I'm now dealing with algae and an outbreak of what I think is cyano. Assuming the lack of Dino's is resulting in increased nitrates and phosphates.

My question is: when is it safe to use water changes and GFO to reduce nitrates and phosphates? The two things that triggered my outbreak originally I'm hesitant to begin doing again. But don't see other options than continuous siphoning. At some point it's gotta be safe to perform WCs and run GFO again.

Thoughts ?
