Alright so I hooked up my sump a few days ago and I can't get rid of the micro bubbles.
I have an overflow box with a clear flex tube as the intake it then goes into one side that overflows into a smaller baffle filled with sponges than it goes into the ref part which fills into the return pump section.
I am using a mag 7 pump for the return it is fitted to a clear tube that feeds into a hard PVC
pipe with a valve before the first 90 degree bend. I barely have it open and I still have quite a few micro bubbles and I am unsure how to fix it. I have adjusted it multiple times playing around with the overflow box as well as the ball valve on the return.
Any tips or help?
