Bad cyano

[Aquattro]

chemiclean. Just works. If the cyano comes back, then figure out why. If not, you're done. I've used it the two times I've had cyano outbreaks over the years, and nothing bad happened.

Chemiclean used here...works great. Never had it come back.

check out your salt, it maybe a bad batch. I used to get cyano with H2O and after switching to Reefchem reef salt I never have any problem
