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 chunks of this falling off my glass as I clean. I assume my decrease in Calc and ALk ; plus my increase in Mag has made it easy to come off.
Anyone that needs it to seed their tank LMK.
