I have injected my Aiptasis now three times and I cant seem to get control of them. I have 40-50lbs LR (20 +/- indiv. rocks). There is nothing else in the tank, other than LS, pods and worms. Is there anything I can do to take care of this plague, other than treating the whole tank? Can I just take out the individual rocks and soak in lemon juice for a short time, rinse and put back in tank? I can shake the rocks a bit in tank to disloge and loose pods and worms first. Next step is to get some Pep. shrimp, but the tank is still new and I don't know if the shrimps would fare well. All parameters are zero, but just not that mature. 2 mos old.
