Saltwater Swimming Pools

If you recently found a flaky white substance in your saltwater pool and you have a cartridge filter what could this be?

Are these loose flakes? Could be calcium deposits if attached to

pool walls etc. Are you adding proper amounts of muriatic acid? Are

you testing your pH? Alkalinity?
