This pool is about 22K gallons for a rental house. I plan to have it re-plastered when the weather cools down. I service it once a week. I don’t want to rely on my tenants to add chemicals, as they tend to be inconsistent, so I want to install an automatic chlorinating system. This city has banned salt based water softeners, and salt water is not allowed to be drained down the sewer or the street. I also have copper pipes in this pool. For these reasons, I have decided against installing a SWG. The other option seems to be a peristaltic pump system, but I’d like feedback to determine what my best options for purchase and installation might be.
This area is very hot (Southern California). I’m thinking it would be best to add all the chlorine at the start of the filter cycle, so it can enter the pool in the dark rather than in the sunlight. I plan to input the chlorine after the filter, just before entering the pool. I’m thinking of using a recycled 50# tab container to store my liquid chlorine. It holds about 6-7 gallons, and I figure that should be more than enough to last a week, before I add more 10% chlorine. I may put this container in a larger one and fill the voids with insulation foam, to reduce chlorine deterioration from heat and sun.
People seem to focus primarily on Stenner pumps, here. Which pump (model #) would you recommend, allowing me to both input up to 1 gallon per hour, yet also allow me to adjust the flow to keep the chemical balance stable? How would you suggest I wire a timer, connecting it to the filter timer, so the chlorine is released starting about 10 minutes after the filter kicks in and stays on for about an hour? I only have 110v available at the pool.
I’d appreciate any installation suggestions, based on what you’ve discovered has worked well in hot, sunny conditions. Thank you.
