I see, I am running a Dart connected to an OceansMotion as a return and the overflow is keeping up with no problem. I was thinking of maybe switching it out for a HammerHead and ditching the idea of using the penductors in a closed loop. Hopefully the overflow will keep up if not i'll cut up the teeth like you did
. I hope at that time the two 1" drain will be able to keep up if not i'll have to use the 3/4 " as a drain as well.
BTW, do you have a pic of your filtration system?
