Fritz Maracyn Oxy bad for inverts?

[cdnco2004]

I have a juvenal Salt Water Molly who has a bubble growth on side of head (will attach pics) and was recommended that I use Maracyn Oxy to treat. I am on day 2 of treating with 5ml daily for a 20g long tank. Today the surface of my sand is covered with bristleworms. They all crawled up out of the sand bed. Do you guys think its the Oxy? The bristeworms are moving so not dead. I have never seen them come out like this during the day time. And I am pro birstleworm as CUC so I was not looking to kill them off.

I think I recall seeing it now that you posted it. Will move the one molly. It was only the mollies in the tank. I never thought of the bristleworms. There are no other inverts. Its just a grow out tank for the juvinal mollies. SO I will just pull out the one molly and treat in a qt.

Not reef safe. Your molly may have been exposed to carbonate poisoning from saltwater traces or incorrect acclimation to salt or Viral hemorrhagic Septicemia. Maracyn 2 often helps with this

The moly was born in my SW tanks so not acclimated to SW but SW by birth. Maracyn 2 vs Maracyn Oxy for it?
