I have my pool pretty well balanced, and I was talking to a friend that is opening his Friday. He didn't believe me at first, when I told him how easy it was, and how little I spent getting it ready. He's already sold on the TFP method. I'm going to help him out. His pool is an above ground pool, 15x24', with a 4' depth. Pool Math says about 9300 gallons.
I tested with my TF100 and got the following today:
Water looks pretty clear (peaked under cover)
He has a cartridge type filter. So Pool Maths I should add the following:
70 oz of 8.25% bleach for FC
30 oz of washing soda or soda ash for PH
131 oz of baking soda for TA
50 oz of stabilzer for CYA
Since I need to raise ph and TA, i figured I should use soda ash. Yes? But how do I know how much it will affect TA, so I reduce the baking soda addition? Or can I just retest an hr or so after for TA, and go from there? I figure I should adjust in this order:
Also, he said last year he used tablets, that lasted about a week each. He never tested FC last year! Ouch. We'll get him sorted out this year. But I think his best bet is to get CYA stable, and then sanitize with bleach vs pucks or anything like that. Would you agree with that?
