I have a 20', 52" Intex pool. My CYA is 40. Down here in the SW Georgia sunshine it appears I will lose roughly 2.5 ppm chlorine during the day. The chart on this site says I should maintain a FC level between 3 and 5 ppm. It appears I will need to add 32 oz of 8.25% bleach each day to keep from dropping below 3 ppm.
Here's my summer plan:
Daily - Test FC (late afternoon.) Add chlorine as necessary to boost FC to 6 ppm. Run my 1,600 GPH sand filter 2 hrs in the morning (so I can skim off the bugs that settled during the night) and another 2 hrs in the late afternoon. I will run longer if water is not sparkling...
Weekly or after significant rain - Test cc, ph and TA. Adjust as necessary.
Monthly - Check CYA. Try to maintain roughly 40
What I'm hoping to achieve:
Only have to test once per day (assuming I never drop below 3 ppm FC.
Never have to shock the pool.
My pool will consume two jugs of chlorine per week and will need no other chemicals.
Adding the chlorine in late afternoon will allow it to work all night without loss due to sunlight.
If my daily FC test shows a drop below 3 ppm I will investigate further to see if I have an algae problem.
If my water gets cloudy I will also investigate.
I know there will be variables and I will deal with them as they arise but it really does appear this simple to me. Am I missing something?
