[NYreefNoob]

ok here is some better pic's of my zoo's being taking over and dying, its a reddish color dont think it is cyano i dont have it anywhere in my tank. it started a week after i got some new zoo's that didnt open up. zoo's started to basically melt away. check water para and all good. did a 10% water change 3 days in a row then a 40% water change. tried fw dipping them then melafix dipping as well. now it's starting to spread to other zoo's

not sure what it really is, but it used to grow on my zoos that didn't get enough flow...so what i did was take that piece and blast it with my powerheads and gently pick it off

It's cyano. You could use more flow and you should probably check your phosphate levels as well.

Cyanobacteria.
