Swimmer08 Posted August 9, 2010 Report Share Posted August 9, 2010 I have an inground salt water pool with a cartridge filter. Since switching to salt last year I am getting a sand sediment in the pool that the vaccuum is removing, My pool supplies exoert has never seen this before. Does anyone know what the cause might be?

waterbear Posted August 9, 2010 Report Share Posted August 9, 2010 Post a full set of water test results. I suspect that it might be calcium precipitating out but need to know you water balance to be sure (and not after you have adjusted it either).

NccPools Posted October 21, 2010 Report Share Posted October 21, 2010 you are experiencing calcium deposits from your salt cell Quote Link to comment Share on other sites More sharing options...
Beelzy Posted October 21, 2010 Report Share Posted October 21, 2010 Check the Alkalinity of the water. if it's too high 100+ the salt cell will produce white-ish looking deposits through the return line. If the debris really is "sand" and it's always in one corner of the pool, then a return line is cracked and bringing the sand into the pool. Good Luck!
