Great point, Robbie! SWCG does make chlorine which is one of the B's in BBB, but I guess I wasn't thinking about that when I was typing. I did notice a while ago it looks like some terminology on the forum has changed (TFPC, SLAM) but since I'm hanging out in the Under Construction area 99% of the time I haven't followed how/why the changes.
I completely agree with your assessment of many PBs interest level in chems/balance. Our PB was tickled when he spied my Taylor K2006 kit. He said that was the one he used back when he did a lot of pool service when he first started out, and that I must be serious about my chemistry! He's said many times since that he's never dealt with a homeowner like me - most just want him to build a pool and go swimming and that's that. This has been a double-edged sword for him! :study:
When I probed a few of the PBs about their chemical preferences, two swore by trichlor pucks and when I pointed out the rising CYA issue with pucks, one said I should just use Cal Hypo. I asked about it raising other levels adversely - knowing I was getting out of my depth with my Liberal Arts degree and minimal chemistry classes, and my limited knowledge of one year pool ownership vs his 50 yrs in the industry so not feeling confident to go to battle on cal hypo, just knowing there was something about it that wasn't totally desirable - he then said he would do whatever I wanted but he'd advise against BBB.
I understood that one had been burned by flagstone coping disintegrating and causing problems with customers, as one of my discussions with each was our coping choice being more durable than the existing calumet stone (old school oklahoma flagstone) we currently had on the pool. When I said I didn't want the maintenance of sealing any stone, it shut the door on stone coping, so I said that we could then have the SWCG, and he pointed to our wrought iron fence and metal patio furniture and said they would be ruined by salt. When I mentioned a peristaltic pump being on our wish list as an alternative to salt, he said those were mainly for commercial pools. I sort of gave up on convincing these PBs and decided we could do something ourselves later on.
One guy who came to do a pump repair for us last year does a lot of weekly pool service, and he was strongly against SWCGs, too. He said they do not keep up in our Oklahoma sun, so have to manually add chlorine anyway, and are prone to needing lots of repairs. Again, he said we should use pucks but he said the CYA in his pools stays a manageable 50 with the rate of evaporation/top off here, so was at least conversant with the issue and said it hadn't been a problem in his experience. However, he was nice enough to tell me where they get liquid chlorine and said they do occasionally use it. When I first started BBB, I checked Leslie's for liquid chlorine and they told me it wasn't legal to import into our state. The pool service guy said that wasn't true, they sell it in his shop. Another PB told me it could be found at Ag stores like Atwoods or even some Ace Hardware locations, so it isn't illegal.
We do have a bluestone retaining wall going in about 4 feet from the water, so I don't imagine it would play nice with an SWCG unless I was willing to do the maintenance of sealing it periodically?
Also - apologies, blueskies!
