28' round
44-46" water
Jacuzzi 190L sand filter
Inline feeder with 3" chlorine tabs

This year we put in a new liner with about 55% well / 45% delivered water. For 6 weeks the water was crystal clear with chlorine around 4-5 and pH around 7.2. I was gradually dialing down chlorine but never really got it much below 4. We had solar cover that kept it 80-85.

Other factors could be farmland is all around us which was sprayed and heavy rains that added up to 1.5" water. The pressure in filter does not rise over time so it had not been backwashed until I read that a channel could have developed. At opening I put in skimmer a little talcum-like stuff I was given that dealer (now closed) said would help filtration.

It rarely went 3 days without being used. Jet was pointed so it would cause ripples on surface when cover off.

The test kit I have (not strips) produced following results:

Chlorine - at least 5
pH - 7.6
Alkalinity - 210
Hardness - 0
Stabilizer - 75-80

From other reading it seems I should add a bunch of liquid chlorine (bleach) but I wanted feedback on what should be done to get it clear in 10 days and maintain that more easily.
