I posted before that my SWG cell went out around two weeks ago. During that time I used bleach to maintain my chlorine levels. My pool guy (just used for supplies and repair issues) brought a functioning cell (two days ago) to use in place of my broken one until the new one comes in. After turning on the SWG, the level read 1500. Just a week before, before the old cell went bad, the level was 2900. Would a two week span of this cause my salt levels to drop that low under normal operating conditions? We had about 4 inches of rain one day and I had to drain water out to get below the top of the skimmer, but this didn't affect my other numbers, so I wouldn't think that the salt would be affected that much either.
I have added 3 bags of salt and now my reading is 2100. According to my calculations, I should be closer to 2500. (I added the salt, left the SWG off for 24 hours, then turned it on and it's been on for about 14 hours)
Is this loss normal when adding bleach to the pool for CH maintenance? I have only otherwise had to add one bag of salt since startup in April (other than the large startup dose).
