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.
Since it's only a 10 gallon I would do a 5 gallon water change then like 2 days later I would do another 5 gallon water change. That should knock it down. Maybe think about a hang on the back refugium with some cheato in it.
