Chemmiclean aeration emergency!

[jhaggerty1990]

I used chemi clean about 2 hours ago and forgot to turn my skimmer back on after feeding earlier. I noticed some corals closing and immediately thought chemi clean sucked all the oxygen out. I took the top off my skimmer, threw in an airstone, and aimed power heads for more aggitation. Will my corals be okay in that short period of low oxygen?

Probably ok.

It’s not the Chemiclean that consumes O2, but the dead bacteria (including cyano) that decompose and reduce O2.
