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 chaeto in my sump and it only gets light for 5 hrs per day and its fine.
You can cut mesh media bags to create a net to catch the chaeto pieces before they clog your sponge.
