Its the gift people give you with frags
Is it truly impossible to get rid of?
Not impossible, but there is no surefire way to do it. Some raise pH to 8.8, some go lights out, some NEVER do water changes until it is gone, some break down their tanks and replace/dry out their rocks, and many just give up and leave the hobby. If I had it in my tank I wouldn't feel comfortable selling anyone a frag unless I did a complete break down and replaced all of the rock.
Thanks,
I've never had it and hope I never do. Since it's algae, I'm guessing that dipping new coral in something like Coral Rx won't keep it out of your tank...?
That's interesting. How would u dose hydrogen peroxide?
It works I can tell you from experience. It also works on HA and Bryo.Spot treatment with hydrogen peroxide have been reported to have some effects.
That's kool. And that doesn't do anything bad to ur corals?
