I joined the forum earlier this year and started using the tfp method in May this year. Pretty much stopped doing everything I did the first year as a pool owner that the pool store told me to do. Drained 80% of my water got my cya down to 40 and started using the tfp method.
All I did this summer was dose nightly with 10% and add acid twice a week. Got a full test kit and a speed stir. Began the first month testing the fc and ph nightly and recording the results. Did a full test every weekend including fas-dpd test
Pretty much added 32-42oz of 10% nightly and added acid twice a week once I got my TA to 70. Ph was rising rapidly at both 90 and 80.
Summer test numbers
Fc8 (after dosing)
Fc4-5 (before dosing nightly)
Ph7.4-7.6 (avg test numbers)
TA 70 (started at 90 after drain and fill)
CYA 50 (started at 40 used a couple tabs to bring it to 50 then haven't used one in 4 months now)
So all that being said the method is totally legit and works awesome. I averaged 30 mins a week on pool care all summer that counts nightly dosing, testing and brushing and cleaning out the skimmer and pump basket.
My neighbors are totally jealous of how my pool looks, feels and how crystal clear the water is. Other then my initial slam after I did the drain and fill all I did was add liquid chlorine. Didn't use a ounce of dichlor, trichlor or any additives all season besides acid.
Haven't got any friends to convert yet cause they don't understand, but this method is simple and easy and the learning curve isn't bad either just takes some dedication.
Think I will eventually get a liquidator or a strenner setup other then that I don't think I need to change anything I'm doing
