Pressure from Jet Decreasing

[JohnT]

The Baquacil remnants can cause the sand to clog quickly.

Air bubbles are coming out the jet after I backwash and rinse. When it is first turned back to filter bubbles come out the jet for a second then it stops.

Something else when I put the valve on by pass to pool the pressure runs 15psi and the flow from jet is strong. When I turn it back to filter the pressure decreases does this mean the sand is clogged or a suction leask or maybe both.

As JohnT said you need to change the sand after a goo conversion. Momentary bubbles out the jet, I wouldn't be concerned. If they are sustained then there is a reason.
Just a side note...you can edit your post up to some time limit after the original posting but I'm not sure what that time limit is yet.
