Hi all,
This is a great site, I've been searching for answers everywhere and so this is great, the pool calculator is GREAT.
Anyway, I have a large non-traditional pool. In full sun!!!
37 X 49 oval
approx. 40 to 42k gallons (it slopes like a pond so the depth varies)
Black vinyl liner
Pentair sand dollar 26", 75 gph with Zeobrite, 1/2hp hayward super pump (will be getting 3/4hp)
The pool lives in Vermont
I have shocked it 3 times, still chlorine levels barely register (my friends the newts have returned).
I understand now why, I have no buffering so it just disappears.
I have the HTH 6 test kit and it shows:
TC .5 (or possibly less)
PH bet 6.8 and 7.2 (a bit hard to read)
TA 30
TH 70
CYA 0 ( the solution NEVER turns cloudy).
After reading about chlorine here I realize I should just use liquid chlorine or bleach, I had been using HTH 3-1 tabs and having no clue how much, how often.
It seems I should add Washing soda to boost both PH and TA?
Would this be better than Borax and/or baking soda?
How would I put that in, broadcast or slowly add by the water entrance?
According to the pool calculator I need 4 gallons (or 13 lbs.) of stabilizer to increase the CYA, seems like a lot!!!
Being a newbie I'm so afraid of putting to much of something in...
So, should I not be afraid and put lots (4 lbs I think) of washing soda in, almost 2 gallons of bleach and lots of stabilizer???
All at once? Or spread out over days??? Also can it be swum in after adding the chemicals??
I think I've asked too many questions in one post..
Thanks so much!
