Finally getting water into my 40 breeder today and working on tuning it. I do have a gate valve but no adjustment to it or reducing my return pump seems to quite it.
I’m not sure how long of a pipe in the overflow box I need to cut, it’s making considerable sucking noise.
Additionally I have a custom sump kit but the splash box pipes are super long and intricately cut with a design and I have it nearly all the way down to the bottom of the sump. How far below the surface of the water do I want to extend? I heard if they are too long the bubbles and I assume noise get out of control.
tight stand so please don’t judge my cable management, I have a GFCI circuit, and working on making it safe.
