Fishmanmike01, I already purchased the tank/stand/weir/ and bulkheads so ill probably stick with my current tank.
Acropora, I will try to size everything up. The single bulkhead i purchased is a bit of a monster with about 2" ID and a 2.5" recommended hole size. It looks like i might be able to get two 1"ID 1.5 inch hole sized bulkheads in there however they would need a 90° bend to point up because everything is coming in through the rear glass. Would this bend effect the herbie system?
