I have been using the TFP methods in caring for my pool for 4 years now and have truly had a TFP. I have been guessing at my pool chemistry except for the daily Chlorine and pH test with the inexpensive test kit. This year we have had a lot of rain and cool weather. I had started to see some green dust around the edge on the bottom of the pool. I started keeping the Cl2 level a little higher (3 to 4ppm instead of 2 to 3ppm). It was not getting worse, but it was not getting better. I decided to get the TF-100 kit and quit guessing at the levels. This is what I got this A.M.
pH-- 7.2-7.3
FC--7.5
C.C--0.5
CH--275
Alkalinity--50
CYA--45
Borate-- 30-35
I use liquid bleach/Cl2 @10% that I get from either Menards or Big R's when on sale in the spring for an average of $2 a gallon. I use Muriatic acid. I keep 1, 3" tab in a floater to help maintain the CYA level. Now with these test results, I am going to add some borax and keep the Cl2 higher and allow the pH to come up to 7.4 to 7.6 and see what happens. Also, I will keep the filter running 24 hrs for a couple of days(I usually only run it 10hrs).
I have a 24ft round vinyl pool with 150# sand filter, current temp. is 72F
My experience to date with TFP methods has been great. Chemical costs have less than $80 a year, down from $250-300 and I used to run the filter 24/7 from about June 1 to Sept. 15 and now only run it 10 to 12 hrs depending on bather load. Just about always sparkling clear.
