I have some 30 gallon tanks with 1" bottom drains. I'm thinking about getting the reducer in the link below but the inside looks like it was cast by a pre-schooler in their sandbox.
Any reason to be concerned with how rough the inside looks?http://www.ebay.com/itm/304-STAINLES...item3ccb7d5c94
no, i would not be anyway.
Nothing to worry about. Unless cats had been using the sandbox.
