Just curious, for the members up north, when opening your pools this season, how much chlorine did it take to get your pool under control?
I opened my pool Saturday (May 23rd). The water was clear but had some sort of Algae covering the liner. I brought the chlrine up to shock levels ~ 12 PPM (no CYA at opening) and have been keeping it between 10 - 15 PPM. After brushing the liner the water immediately went cloudy for 3 days. I know have it crystal clear.
At this point I have used 18 96 Oz jugs of Clorox (6%), 4 bags of shock (43.5% available chlorine), 4 pucks and 48 oz of granular chlorine.
I have been adding 40 ounces of stabilizer which are almost completely disolved. As this morning the numbers are:
TA - 130
Calcium - 40 - Vinyl therefore not too concerned
FC - 8
CC - .5 - Added another 6 PPM of Chlorine before going to work.
CYA - 30
This is only my third opening (first done by the Pool Builder). Last year I went through a lot of chlorine as well, unfortuantely I did not keep track of it. I feel I am under control but is this normal? Does everyone else go through this much chlorine when opening? Granted I had Algae but adding that much chlorine seemed uncomfortable to me.
