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 a pentair 80W on my 260g. I run it on the protoza flow rate and my temp would climb from 78 to 83 degrees if I let it. So I had to get a chiller to counteract it.
