What kit are you using?

Add some 20 Mule Team Borax (laundry aisle at Walmart). Maybe a cup at a time. Wait a couple hours and retest. Redose if needed until you get the pH right above 7.0. Then, turn your return jet eyeball upward to try and create as much splashing on the surface as you can.

One thing you did not mention was your chlorine levels. Do you have a chlorine reading?

How much stabilizer did you put in?
