I am planing on buying a powder brown tang soon will he/she eat red slime algae. I have a 29gal. tank I know thats a little small for a tang but planing on a 150gal.in about a year or so.
+1Tangs eat green algae not red slime which is not algae but a type of bacteria - Cyanobacteria to be specific. Don't buy the tang til the 150 is cycled thru and stable. The Tang won't survive in that small amount of space or water for 1 year, he'll be dead of ick within' a month.
+1 agreed.Nope PH doesn't really effect Cyano - if your PH is low then your Alk is probably low. Try switching salt mixes to Red Sea Reef Pro rather than dose.
As for the Cyano - if your .02 + 10ppm simple remove the cyano with a tooth brush it probably won't comeback in force. When it does just wipe it off - eventually with no PO4 it'll stop.
