salt pool

[shas]

hello, I wonder if anyone would know how many 25k bags of salt are needed when setting up a 75000 litre pool from scratch.

   any help gratefully received,   sharon.

you should ask pool installer as it can be different.i use 4000mg/litre=4g/litre=4,ooog/1000litres=4kilos.

therefore for 75000litres use 75000divided by 1000=75x4kilos=300kilos.or12 bags 25kilos.

you need to check salinity every 2-3 months and top up salt maybe 1 bag each time.

Just a point on checking salinity. My chlorinator (Surechlor 3000) has a facility to read the salt level. However, I find that this consistently underreads, and I was adding far more salt than necessary. I now use Aquacheck Pool & Spa Test Strips, which I buy from my pool supplier, and now find I need to add far less salt and still have good chlorine levels. I'm sure there are other brands available, but don't rely on the inicator on the chlorinator.
