Pond Boss Forums AERATION Systems questions HiBlow aeration issues

Hi,

I have attached pics. It is a new pump two months ago and over the past few weeks have just been trying to set it up. The diffusers are about 2 feet deep. The pond is about 3 feet deep.

The pump is pumping air. I am not familiar with these type pumps so I am not sure how much 'force' the pump should be emitting air with. I can say that i can easily hold my hand against the outlet and it doesn't take much effort to stop the flow but I assume that is the way it's supposed to be.

It is very frustrating because it seems like this should have been a fairly simple project that is turning out much more difficult!
