After reading Lunchbucket's Hydroid problem I think this might work. Lunch post about Hydroids and see how they feed.
Many others have AIPTASIA problems. I have decided to share something.
I was reading alot about AIPTASIA control and destruction with my old setup where it was out of control.
I read the same information again and again about destroying AIPTASIA . After reading articles on RC the information would be so diluted that it was a joke. The main reason for this was hand me down information.
I tried it all. I had a nice looking tank with Stonies getting stung left and right
Joe's Juice is a joke IMO
KALK slurry is a Joke IMO
Peppermint Shrimp are hit and miss.
Lemon juice ? Yeah ok

Boiling water? Yeah sure
I have decided to take out my camera and take pictures of a guaranteed solution for AIPTASIA. Pros and cons...
Cons Increasing Salinity.
Considering in my old setup I used this stuff none stop,I don't see it as a con.
Pros-Destruction to AIPTASIA
This is coming from a person who never cleans his reef equipment with muric acid for fear of contamination. I just use Vinegar and still do.
SOLUTION-READ IT!!!

I no longer have this problem since cooking my rock but I wanted to share it.
