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.
Maybe put the bio media in the chamber with the return pump? It doesn't need a ton of flow
Also if you use cheMI pure elite you can do away with the gfo (as it has some in it) so that can free up space
