Well this is interesting. Without repeating everything from a post I made as a newbie here, my results from my own pool test, confirmed by a test from Leslie's pool store, gave me decent results on FC, but they tested for Phosphates and that came out at 1500. They said that was high, and risks an algae bloom.
Other results are:
CYA ~ 20 ( was 31 from another pool store) just a couple days ago.
TA: 150 (this one is strange, because I tested it myself with a new kit and came up with 80 to 90, and the other pool store told me it was 75 just a few days ago. I only added 4 lbs of sodium bicarbonate, so I see no way in heck did TA go up from 75 to 150 1 day after adding that stuff)
Since this is a brand new pool, and we filled it with water from our local muni on July 20th this year, which gets its water from Lake Michigan, the only thing I can conclude is the water CAME with the 1500 phosphate level.
My water is crystal clear and there are no signs of any algae, so I don't see a reason to spend $80 to remove or lower the phosphate level.
Obviously I need to get the TF100 kit pronto since these pool stores give such wild and random readings. I read it here that other people experience that, and low and behold I am getting the same **** experience.
Heck, they could add all sorts of stuff to your water, or tell you anything they want just to sell you chemicals !
