Plumbing

I'm getting ready to add a sump to my tank this weekend (I'll have a separate blog for that operation) and currently have the system mocked up in my shop using an old 29. The eshoppes nano overflow box is really noisy. If I run my pump wide open it burps and slurps. If I add the pre-filter sponge over the outlet that quiets things down considerably, but with the alage problems I've had I'm afraid it'll clog up frequently. There's no room for a Durso style overflow, the box isn't wide enough. ...
