In summer, I get tons of leaves, dust, pollen and other debris blown into the pool, I kind of have to run the pump throughout the day so I can jump into the pool whenever I want without a major clean-up first - my pump run time is skimming driven rather than chlorine generation driven.
In the end, I settled around 10 hours that I run the pump with two short breaks from morning until evening. Like that, one bar in my SWG settings (I have 8 bars, so I can adjust my chlorine production in steps of 1/8 = 12.5%) corresponds to about 0.5ppm in FC, which I find a reasonable quantisation for FC-adjustments without fiddling with the run time.
In winter, I don't get as many leaves and I don't swim anyway, but I keep the pool open. Then, I reduce the pump run time drastically. I need max. about 0.5ppm of chlorine in winter, don't need much run time for that, but I still like to run the pump for a few hours to keep the pool clean.
Just a thought, where should the pool jets point ? Slightly down, or just under the water as long as it’s pushing towards the skimmer ?
