Hello, i found TFP last summer (thankfully!) When we put up our first pool. I took the cover off today and tested. It's an above ground 6500 gallon intex with sand filter and swg. Could you please advise on which chemicals to add first? I'm fairly certain chlorine is first but how long do I wait to add stabilizer and baking soda and salt? I have my test results from my tf-100 kit. Thank you very much.

As you say, add chlorine. Immediately followed by the other items. The salt can wait until the water is warm enough fro the SWCG to operate.

Today's test results:
Ph 7.2

CC less than 0.5
TC 9.5

TA 90
CYA 70
temp 68 degrees

I have not added salt (last test on 4/3 1430), waiting for new salt test strips to double check. I did turn on the swg and it works with no errors or low salt warnings. I think I'm on the right track. If you have any advice or notice anything in the test results that I'm missing please let me know. Thank you😊20200407_122524.jpg
