Throwing a small powerhead in there will not hurt and could help. Siphon the cyano off as best as you can, make sure you are doing water changes with good water, and make sure you don't have any phosphate issues.I need to fix my sump situation, the cyano has taken over everything in the fuge area. Is this ok and just part of my cycle? Or should i try throwing a small powerhead in there to get some more water movement?
