Well I'm having trouble with baffles (wasn't leak proof and turned out GE silicone 1 kitchen and bath is not for aquariums) so I've been contemplating a baffleless sump. I'm only using a 10 gallon and I was thinking just have the overflow hose over some filter pads and next to that is some ehfilav and biomax and then the return pump. Think that would work? Plus I haven't tried yet but i plan to tommorow but how do you remove the silicone?
