I have an attached spa for my recently completed in-ground pebble surface pool. The pool is 15 x 30 and the spa is 7 x 7. The spa does not have its own skimmer or pump and relies on the valve settings to move water in and out as well as recirculate. I have a Jandy iAqualink system so I can program all of this on a schedule. I also have a SWG for the system.
The question is how often I should be running the spillover function (pumping pool water into the spa and letting the spa spill back into the pool) vs recirculating the spa water every day. As of right now, I run the pump for the pool 11 hours a day (6am - 5pm) at a low RPM. At 5:00 pm I run the spillover function on the spa for 30 min (with the chlorine at 80%) and then the recirculation of the spa for another 30 minutes (which the chlorine at 5%). So far it seems fine, but I am worried about over/under chlorinating the water in the spa. I have checked the Cl somewhat regularly and it sometimes differs by 1-2 ppm one way or the other. We have been using the spa somewhat frequently (when we do it is in recirculation mode) so it can be hard to figure out if I'm under or overdoing it also because of usage.
Any experience with the best way to manage this?
