Hey guys, I'm new to this and was wondering how this overflow works? I believe the first chamber with the whole in the bottom is so you can attach a bulkhead and then put in a durso standpipe for the water to drain down quietly? Is that correct? But what is the second chamber for? It's just an open rectangle all the way through? What does it do? How does the water return? What would you guys do? Thank in advice this will help me a lot!
