hello all! recently got a reefer 300xl going - great system - anyways, i'm running a sicce synra 6.0 pump at about 70% normally and then turn it down to about 20% for feeding. After about 60 seconds, the plumping starts making noise - it seems that, of course, as the pump is pumping out less that the sump is taking in, that too much water is making its way back down into the sump so i'm getting noise and bubbling out of the plumbing.

i can of course fix this temporarily by closing up the valve however then i have to find the right spot again when feeding is done and i ramp the pump back up to 70%.

am i doing something wrong here or is there a better way to do this?
thanks!!
