I set up a rubbermaid tank and let it run for 6 months. Then I added a bubble tip anemone and within two days it expelled its zooanthellae and slowly died. The only thing I could find different about that tank than my other ones is one pump shocked me when I touched the water (a pretty good shock). Could that be enough to kill an anemone? I've never had trouble with any other tank so I'm kinda at a loss to understand. Any thoughts?
