So water testing my new setup and all is good except for the noise. I have a dart for the return pump and an external overflow. The overflow has 2x 1.5" bulkheads in the bottom and one on the side for an emergency drain. I found that if I have 1 drain elvated slightly forcing most of the flow through the other that is the quietest mode. Only problem is the. That every few minutes a vortex forms and makes a loud sucking noise. I forgot to mention on the outside of the bulkhead I have it T'd with one side going up to open air the other s the drain.
The dart also feeds 3 other tanks and the skimmer so the main tank isn't taking all the flow.
Any suggestions?
