I've recently experienced some green type of algae, got some GHA but also some green algae that's like coating the rock like a green film and another type that's almost like a green powder type of algae. Ill attach some pics, I've been skimming a little wetter than normal now, running a gfo reactor now and increased water changes and bought a jebao wp25 to increase circulation. Never really had a problem before just hit recently and keeps getting worse. Only thing that's changed is took an aqua clear filter offline and started running the reactor and adding 5-6 drops of selcon and or vitachem in food occasionally. I will cut back lighting some and vitamin supplements also, any other ideas? Not any high phos or nitrates showing up on test but I know some are highly unreliable. Thanks for all help!
