Help ID this stuff killing my zoas

[greenhead]

Kinda looks like cyno but it won't come off. Has taken out one colony and is starting on this one. Area has good flow and nutrients are low.

Gonna dip them in revive tonight. Its on one acro plug also but doesn't seem to bother it.

Can't tell from the pick but dipping zoas in furan 2 will never hurt

Nope. Algae…

Hydrogen peroxide dipping:
20% H2O2 and 80% tank water for a minute or 2.
Rinse off in another container with tank water before return to the system.
Be happy!
