Pump Issues

Not likely but it could just be the plumbing, the pressure drop on the pump input might be too low which could in theory liberate dissolved gasses. To test for this try restricting the output and see if the bubbles stop.

pictures speak... do you have any?

The ty-wraps look a little ghetto but I tried to tighten up the connetions in desparation...

How are to taking water from the tank?

There is a 1" bulkhead behind the rocks that feeds the closed loop pump. And 2 outputs from the closed loop pump.

The bubbles are definately coming from the closed loop and not the sump pump.

Assuming that the line was primed properly and there isn't air sitting someplace occasionally being dragged into the pump, you might want to try plugging the C/L returns and then while under pressure the leak might reveal itself.
