Little info 1st on setup....200gal Acrylic tank with 5ft overflow with 3 2" durso's draining into a 3" pipe into a 35gal sump (soon to be replaced with 47gal sump), my return pump is a Sequence Hammerhead with 2" inlet and outlet with a three way into 2 1.5" returns and the third line splits again into my chiller and refuge. I have ball valves on everything to control my flow. Tank has been up for just over a week now and last night i started getting bubble blast every couple of mins in the tank. At first i thought it was low water in the sump, but even though i have more in there i still get the bubble blast in the tank. I should mention that on the inlet side of the pump inside the sump i have placed a small 2" pipe with a 45 degree angle facing toward the bottom of the sump, thinking it would be less likely for the pump to suck air if the water lever drops from evaporation.
So, any ideas what to ck? where the air is being sucked in from. Only other thing i could think of, is my outlet for the refuge is at the water level and the flow needs to be increased so mater water and less air returns to the sump, but even that being the case it returns into a filter sock for that very reason...cut down on bubbles. I am at a lost!! :(
