So my tank has been running for almost 6 months (turning 6 months tomorrow) and I feel like I’m on the tail end of the ugly phase. I had diatoms for a week or so that turned into a mix of diatoms and brown cyano everywhere, then mainly just staying on the sand for a few months and now it has turned into something that looks more like typical cyano (just on sandbed). Is this cyano and should I treat it or just get another dose of patience?
