Phosban Reactor

[Gizmo]

I've never had a problem with hair algae (knocking on wood) But it worked great for cyano. I have a tang and two rabbitfish that do great work at any algae on the glass. Last time I had a cyano outbreak and it was bad, I shut down the lighs for 2 days. Kept them down to ~5hrs a day and ran phosban, after the 2 days, the cyano was completely gone, it had turned into what looked like detrius, the crabs and such had it cleaned up in a day and the skimmer was full, but I havent seen a hint of it since. (again knocking on the damn wood)
