Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I have success controlling aiptasia in my tank with peppermint shrimp. Just one in my 90 gallon tank keeps any new polyps from appearing. I also use a needle and syringe filled with calcium hydroxide paste. One drop on each aiptasia kills them in minutes.
