Thanks to the help and suggestions I got here, I have finally narrowed down to peristaltic pump as the best option for my chlorine automation. SWG was a contender until wife tried a friend's salt water pool and didn't like the feel. Well, that was it.
I plan on going with Stenner pump + tank combo. Due to the high electricity rates in my area, I plan on running the pool pump in high speed for only 2 hours, and I plan on doing the bleach injection during that time. I am wondering if there will be a problem with getting a "large" pump like 85MHP17 and run it for like half an hour? Based on my spreadsheet calculations, running that at half an hour with 6% bleach at setting of 9 will get me 1 FC. I think there is a lot of flexibility to increase the bleach injection due to temperature and bather load and still keep the stenner run time within the 2 hour main pump run time (I can go up to +4 FC if I run the Stenner for 2 hours).
My concern is the "rapid" injection of bleach. Intuitively it doesn't seem like a concern - I'd be injecting 1/3 gallon of 6% bleach over half hour into pvc pipes that should not be hurt by belach anyways. But I figure I'd make sure with the experts here first.
Thanks!
