Um, I don't see what the problem is. You threw in bags of...cal-hypo or di-chlor and it protected your pool over the winter. Did you test your water in the spring? If the #s were acceptable why change?
BBB is a way of thinking more than a set of rigid rules. There's a time and a place for Di-Chlor, Cal-Hypo and Tri-Chlor, as well as bleach.
Carl, you may not have enough of her thread to know but her CYA is high and her fill water is high in CH. So, bleach is probably the better choice for her.
@CarlD: mary jo's pool's CYA is 150 and the CH is near 700.
@mary jo: What CarlD seems to be getting around to is:"If shocking the pool worked in the past, might as well shock the pool now" which is your plan. Watermom's suggestion of using polyquat 60% is probably a good idea too. Are you going to have the pool guys winterize the equipment again this year or do you plan to do it yourself?
Well, I would agree with that. But it doesn't indicate a major change in strategy, merely replacing problematic chlorine sources with our fav...bleach.Quote:

Sounds like a plan, thanks, got it.
@BigDave: I'll definitely have the pool guys winterize the pool- it's something I don't want to tackle at this point.
I promised the kids 3 more weeks of swimming so it should be plenty cold when closing time comes around. thanks
Hey. You mentioned that you were planning on retesting CYA. Did you? Just curious
If you can, take video of the closing to help you remember.
@FBU: cya tested a bit higher: 170
@BigDave: That's a good idea. They also suggested that I have my pool heater "thermo regulator" replaced this year.
