Hi, I'm Oscar, new to the board.
Just bought a house with an IG pool, and luckily it was in decent shape to begin with. Got my TF100 today, ran a couple tests more than once to confirm accuracy, here are my values today...
80 deg F
I know CYA is high, debating dropping some water and refilling vs waiting for rainy season to kick in in a couple months here.
CH a little high too, same debate.
Previous owner had a pool company come weekly who used stabilized tablets in a floater, thus the high CYA. I left it until today when I could run good numbers myself, will now manually chlorinate, most likely with pool store liquid chlorine.
I understand the FC number is about right per the CYA chart, but does this not make the water seem overchlorinated to the swimmer? I've seen it said that over 5 ppm is high enough to close a pool. Pool math also tells me that shocking will take about 2.5 gallons, this is to be done weekly?
Got some other issues, but will get to that later, chemistry first, pic here... http://tinyurl.com/mmf27hy
