I was under the impression salt in a pool lasted quite a long time. so about 3 months ago I got my pool up to 6000ppm (by adding 200kg of salt, it was at about 5000ppm) and haven't tested salt levels since. I tested just the other day after some heavy rain and I am back down to 3000ppm. It is a big pool, 230 000 L which means i will have to add 700kg to get it back to 6000ppm.
How long does your salt usually last? It is wet season and the pool as overflowed once or twice but i didn't think we would have lost that much water..
thanks in advance.
