Looking for advice and comments on the status of my pool and conversion to SWG
24,000 Gal In Ground Plaster, 60 sf PacFab DE SS filter (Orig Filter)
Approx 17 years old, Polaris 3900 (New 2010)
Pentair Challenger Pump (new 2008), Hayward Booster Pump (New 2010)
Auqa Rite T-15 SWG (New 2010)
Issues: High CYA, Black Algae, Quick to Bloom Green Algae, Five foot dia oak tree shades 50% of Pool but also adds lots of organic matter
Test history since test kit came in:
pm pm pm am pm pm
9/8 9/9 9/10 9/12 9/12 9/13
FC 8.2, 15.5, 11.5, 8, 8, 5,
CC 0.2, 0.2, Slight, 0.5, 0, 0,
PH 7.6, 7.8, 7.6, 7.6, 7.6, 7.6,
TA 100, 100, 100, 90, 90, 90,
CH 190, 210, 210, 170, 180, 190,
CYA 200, 200, n/t, 60-70, 50, n/t,
9/8 Major 10" Rain Mud flow in Pool, green brown water, added 5lbs Cal Hypo
9/8-9/10, Filter and Pool Cleaner extra run time, back wash pool clear
9/10 Start SWG process, Drain 40% of water at back wash, add 1.42gal 6% bleech, add 13 40# bags of salt
9/12 am pool 90% full at testing
9/12 pm swg started, 50% run time, Initial salt showing 2,900, add 2 40# bags of salt
9/13 Salt 3000, nothing added
Pool looks best it has in years as of last night (9/13), clear as a bell. Water has stayed balanced through all the changes.
Questions:
1) Should my farthest return have a cloudy look when the SWG is running? More pronounced at start up. Closer returns do not have this visual look.
2) CYA is lower than Auqa Rite suggest. Can I just shock with Di Chlor to raise over time or do I need to buy CYA? After fighting CYA for the nine years we have owned the house, I am viloently apposed to buying the stuff. I have 35 one lb packages left over from my days before TFP.
3) Will CH rise again when I add more salt to get to 3,200-3,400 ppm? If not, should I add CH?
4) TA is close at 90, my thoughts are to just watch and see what happens, agree?
