Magnum polishing filter gassing
I seem to be having a problem with my Magnum polishing filter outgassing. The first time it happened I thought it was that I didn't have the top on correctly or I didn't fill the canister before putting it back together. It's still doing it. The filter is safely underwater, so it's not an air leak. It's to the point that there are a plethora of tiny bubbles floating in the tank. Any ideas what could be causing it and is it harmful to the tank or water chemistry?
