Winterizing BBB method

[Jakebear]

This year will be the first year closing using the BBB method.

We’ve had the pool through 4 winters so far and have never blown the lines out or lowered the level in the pool. All the pool piping is SS clamp type, black plastic like you use in an underground irrigation system which can be frozen.

All we have ever done mechanically is drain the solar system and disconnect the pump, filter and take them inside after a good cleaning and seasonal “once over”. We remove the skimmer valve and put “Gizmo’s” in the skimmers.

Chemically, we have used winterizing kits, sampled, shocked and circulated monthly as long as there is no ice on the surface. This year I need help with that part since I do not intend to buy a “Kit”.

I plan to add a dose of PolyQuat and raise the chlorine level before shutdown. I will continue the monthly sample and circulate routine ---- How much poly and how far to raise the chlorine is my dilemma, also is there anything else that I need to add?

Current numbers are:
Water Temp 73
pH 7.5 by titration
FC 5.8 ppm (FAS-DPD)
TC 5.8 ppm (FAS-DPD)
CC 0 ppm (FAS-DPD)
TA 80 ppm (by titration)
CH 230 ppm (by titration)
Phosphates <100 ppm
CYA = 45 ?? (turbidimetric) (I have drained 6400 gallons and will let it refill with rain and well water, which should give me around 30ppm or less in the spring.
