I finally got my K-2006c test kit and ran the tests. Here are the results:
FC .8
CC 3.2
Alk 220 (250 when I did the high method)
Calcium 475
Ph 7.6 or 7.7 (it was in between)
CYA 200
It's an old pool and aside from the 1/3 water change we just did, I don't know if the previous owners ever did a water change so there is a lot of stabilizer, calcium and phosphates ( 3847 by pool store computer). How much liquid chlorine would I have to add all at once to shock this pool? I need to learn more about the SLAM process, but it sounded like it used a lot of chlorine.
We talked about doing an almost complete water exchange using the tarp method, as the pool water truck driver mentioned he had done that before, but with the pump rental, tarp and water, it would run us about $700 and right now the pool is clear and beautiful, so it's hard to justify spending that amount of money. I have let go of my trusted Trichlor and am using only liquid chlorine. With the cover, it holds its level pretty well for days.
I know I don't have much free chlorine. What would you suggest? (15,000 gallon, fiberglass pool, circa 1997, newer Pentair pump, old Jacuzzi Triclops filter and Hayward H200 heater, with an automatic, dark, opaque cover that's on most of the time).
