i tried that, but they came back double what i had before. i've tried peppermint shrimp and they don't seem to be doing much. i've tried the aiptasia control by blue vet (i think the brand was), that worked for about a week now they're back double what i had before i used that stuff. my polyps are starting to close from the stupid things. i have so many on my rocks some places i can't even see the rock. i don't know what more to do.
