So, I have been fighting this...whatever...for the last 6 months or so. I thought it was cyano, but not 100% sure now. It's not as "sheety" or maroon/dark as what I think cyano is, but close enough.
I have treated w/ ChemiClean 4 times now. 1st time it worked pretty well, but the cyano came back a couple of weeks later. Fast forward to this week and the ChemiClean (heavy dosage) had literally zero effect.
This is Day 4 - barely a dent. Is it immune to ChemiClean now??
Even worse, these Superman Rhodactis have not only been bulletproof, but thriving for 2+ years, and today they are dissolved into shroomgoo. I have no idea if the two are related, but both make me sad, so here we are.
Someone please tell me how to fix this!
