Carl Thank you for your reply. Last night I kept reading and with your advice to someone else earlier I went out at midnight and dumped 1/2 gallon of bleach in. The pump has been running all night.

I just retested and these are the results:

Total Hardness is up from 100 to almost 250
Total Chlorine is up from 0 to 1
Free Chlorine is up from 0 to almost 3
Ph is up from 7.2 to 7.8-8.4
Total Alkalinity still at 120
Stabilizer is up from 50 to not quite 100

Why would the Ph and stabilizer have changed? Is it because I added the bleach?
Or is it because I'm viewing the strip in totally different light this am? With us living in a rural area, I figured the water was very hard.

Our water is still crystal clear with no signs of problems. Should I add another 1/2 gallon of bleach?

Being rural, I will have to check in to finding a pool store to test water and a different test kit.
