Lets see if i can keep this in order.

We added 6 lbs of stabilizer after the drain, (the "pool store" directed us). The drain was not complete, we had roughly 1.5feet of water left.

We have a working pressure gauge, so we will backwash as directed.

I will add the required 5.2 gallons tonight, and test in the morning to adjust back up.

Thank you for the help.
