How do I lower the water level in my pool without removing salt at the same time?
Every year to winterize my pool I lower the water level below the skimmer by pumping water out of the pool. Since I switched to salt, this means I will be pumping about 120kg of salt out as well which I would like to save for economic and environmental reasons.
How do I drop the water level but retain the salt in the remaining water in the pool?
Reverse Osmosis? Large black tarp that will allow evaporation of the water and trap the salt?
