If you followed my "72g Move" build thread you will see I purchased these baffles that should fit a 20g long. The 2 tanks cracked so I opted out for an pre-built sump. The leg on the bubble trap broke but easily glued back and the sock holder also broke but was able to glue that too. It just sits on top of tank frame.
