Howdy folks,
My workload at work has gone up significantly as I've taken on responsibility for a large, long term project and with the extra hours coupled with being away from my home for longer periods, I caved in and resorted to starting a scheduled chemical balance service from a local pool company. The chlorine service is done using chlorine gas injection, which I'm assuming does not affect pH as badly as liquid chlorine can. The pH is also nicely balanced with their service.
The issue I have is that when I use my TFT kit to measure chlorine levels, it's through the roof. The 1st time they injected chlorine into the pool, I'm sure the level was around 25 ppm. I discussed this with the service company and they assured that their target is 6 ppm. They injected chlorine yesterday and this morning, after a full pool cycle I'm reading 15 ppm FC using the R-0871 drop method. When I maintained my own chemical balance (the last 7 years), I've used the same measuring technique and targeted the typical 1-4 ppm levels. Clearly, there's a difference in the measuring process, but not sure how to socialize this with the company. I'm sure others have been through something like this before and just interested in thoughts from other pool maintainers.
Cheers!
