We always kept a round pool running continuously; it has to circulate anyway, and you can just jump in spontaneously when it’s always at operating temperature. It consumes about 60.- per month; however, we only operated it in the winter, and it was outdoors.
We eventually gave it away because water maintenance became a hassle for me. I would have liked to have a dosing system. If it’s good, it costs as much as a pool. It only saves work if it also measures itself, not just doses.
Still, it was simply great. You will definitely have a lot of fun!

P.S. Once the chlorine is used up, it doesn’t eat anything anymore either, so there should probably be little damage in the garden. But doesn’t it still have a lot of other stuff in it? Replace unstable acid with stable, regulate lime…regulate out…algae treatment…when changing water, clean all pipes with active oxygen, etc.? Ours ran at 38 degrees, otherwise life thrives in the water.
