I though i got rid of all my Aiptasias but somehow over night they took over my tank!!! They are everywhere on the GSP, power head, PVC, overflow etc... I just finished reading an article on using a lighter to burn the Aiptasias off. I'm guessing this would be ok on the LR but the GPS and power head I'll try some more joe's juice. i've heard lemon juice but is that really safe to be shooting about 20 Aiptasias with?
