I have a 10k gallon in ground pool with a raised adjacent spa with spillover. This is a foreclosed home I bought, so I have no information on how this was originally set up. There is an Aquatherm Heatpump thats attached to automated Jandy valves so it can switch between pool and spa mode. The tablet chlorinator is before the return Jandy valve so chlorinated water is passed in both modes.
Right now I am paying someone to care for the pool as I am still moving and not there often enough to keep up with it, but I will surely take over maintaining the chemicals myself when I move in. My real problem is more with valves, spillover, and the heater. Originally in SPA mode the heater would turn the Jandy valves to isolate the Spa so water was only run through it. In pool mode though, some water was still returned to the SPA so the spillover/waterfall functioned. This meant that the SPA quickly emptied all its hot water into the Pool which was not very economical. Since I only have one pump I have to run it in each mode for a period of time during the day. I opened up the return Jandy valve and set it so when in Pool mode no water is returned to the SPA. This is all well and good, but I now assume I'll need to maintain the chemicals in the SPA separately.
This being my first time with a pool/spa that are interconnected, I am thinking I'm missing a much simpler way to manage all this.
