So who has had experience with chemical warfare and Cyano? Or other methods? I'm getting frustrated.
I've done lights out twice... definitely works at killing the Cyano off....but then it comes back a day or so later, if not sooner. Before my latest lights off (this is the 2nd or 3rd time) it was horrible. Creeping up over all my low lying corals...it was starting to climb on my Acan, zoas, and chalice and was getting close enough to my hammer where i could tell it was ticked off. Also, lights off is fine...but I can see that my SPS's are not 100% pleased. I assume they'll just come back, but it still worries me.
I have 2 islands...it grows in the middle of the two, on the left side between the rock and the glass, and across PART of the front. Oddly, not on the right side between the glass and the rock. It's even more odd to me because of that symmetry My PH's are 2 Mp10's placed symmetrically on opposite sides so...
Phosphates are 0 ish. Nitrates 0. Lights are all LED, which I thought was supposed to mitigate "nuisance algae". I run HC GFO, carbon and UV.
I've seen it in my refugium too, which is just a partitioned section of my sump. I'm wondering if that has something to do with it and if i should just bomb out my sump, clean it out, toss the macro and rocks, and start over a new fuge. Macro is cheap and I have plenty of dry rubble laying around.
