SO I finally got feed up with HOB and Rena canister filters after they kept failing. My Goldfish tanks sump never needed to be shut down once for cleaning to stop it from clogging. (just refugium weed whacking...) So I switched it to a dual down HOB OFB. It is pretty quite. EXCEPT. for the mag drive pump. it is rattling. I tried leveling it and everything. What do i do to fix it?
