Hi.
I've adapted the calfo overflow design... but I have no idea how to design the return flow for a 100g FOWLR.
Here's how my tank looks like (I have this one built already from Bioresearch Sucat and it will be delivered this coming week )... the only change from this plan was the distance of the overflow from the top... in the plan it's 4"... I had it changed to 5"
Any suggestions or ideas on the return flow design would be appreciated.
Best regards,
JH
