Sump foaming

Just out of curiosity. When you do your water change take the black bio balls out and see what happens it looks like they're collecting bubbles making the foam...

I will definitely try it, they’ve only been in there for a couple days and this has been happening for a while now but worth a shot

Ok, prob too late but i would recommend you switch your drains to a herbie design. You would need to run your returns up the back of the tank. Use both holes in the overflow for the drains. Its super quiet and a much better design. Your problem may be because durso's suck air. That air has to go somewhere.

Do you have a picture of one of those setups? And the drilled holes for the return Are different size than the overflow. Not sure if that will effect anything. Overflow is 1” and return is 3/4”

I'm using a durso in my seapora 75 it's not foaming. It's louder than my hob herbie but work w/o issues. It could also be the 2 1inch pipes going to the 1.5. Could be causing some issues? What that plumbing from the start? Was it foaming from the start with the plimbing?

I’ve changed it up since the beginning but yes it’s been doing it for a while. No clue how the previous owner had the plumbing, but I have the same concept on another tank with no foam issues. Pretty sure it was from the Aquascape putty, I used a crap load of it and introduced it all to the tank in one day. Doing a water change today
