Pool Service Company and Liquid Chlorine / Bleach

[Spensar]

... but keep an eye on the CYA levels!

Spensar and noworries, thanks for your feedback. I, too, am a bit concerned about the CYA growing too high and more specifically about CH. Plus, I've seen the FC decline to near zero toward the end of the weekly service interval. We've had some problems with pool flooding caused by a difficult rain water drainage issue (maybe solved by some new drainage piping). The service company has used lots of Cal-Hypo for shock which (I think) has driven the CH level up to around 400. This week, after a heavy shock to combat some algae, we had blue cloudy water for the first 12 hours or so, finally quite clear and sparkly after another day but with a white percipitate on the bottom which I suppose is calcium and which I vacuumed. The pH was 7.8 (up from 7.6 recently) which may have aggravated the percipitation.

Anyway, the more I think and read about this, the more I think a SWCG might be a better solution. That should reduce the service company workload and get a lot of the not so good chemicals out of the picture, e.g. excess CYA and CH, plus keep the FC level more nearly constant between the weekly service intervals.

Any more ideas on how to optimize this situation will be appreciated!
