Experiences with saltwater pools

It is not yet decided what kind of filter system. If you have any advice, then bring it on. As I said, I have 8m³ of water in the pool.

I would take a 400-liter tank with a 6-8m3 pump. You need the amount of sand. Only then does the filtration work well. Affordable ones are around 300-400€. Sufficient for your pool. With a Speck pump and higher-quality tank, the Bilbao 400 with Speck pump is an option. However, significantly more expensive (just under 700€).

Have never heard of a saltwater pool, but it sounds kind of interesting. It does imitate a bit of a sea vibe.

Is not as salty as seawater. The difference is that chlorine is produced from the water by electrolysis. Therefore, the salt content of the water must be checked regularly (if the electrolysis system does not do this automatically), and the electrodes must be replaced every 1-2 years. Also requires more electricity and, of course, salt. The chlorine content in the water is the same as in a pool that is directly disinfected with chlorine.
