Hi
2nd year using TFP, and due to TFP and my Taylor test kit, my pool has never had better water quality or required less chemicals.
I don't use the frog, threw away old pool perfect, ultra bright, some other stuff from Leslies.
I do use some pucks and old powder until the CYA gets over 35, then go to 100% chlorox - 1 jug every 2 or 3 days.
baking soda to raise TA if it drops below 70, CH is 220, ph is 7.6

my question is about shocking and backwashing periodically.
do you ever need to shock if the FC is kept between 2 and 6 and CC is always 0, CYA is 30/35 and everything else is in balance?

also should you backwash every 3 or 4 weeks even if pump pressure has not risen more than 7/8 lbs?

thx
