Can't Keep Chlorine Up
We have a 16 X 32 inground pool. We have had it about 15 years. We us a mesh cover over the winter and have drained it many times over the winter due to rain and snow.
That being said, my husband has put in 8 lbs of shock over the last week and it is still coming up very low.
We had this hellish nightmare only one other time and that turned out to be "too many disolved solids". As I previously stated the water had been very diluted over the winter, so that is not likely.
*Computerized readings are all within normal range.*
We have done all the obvious things to ready the water for swimming. Algeacide, Shock, Pool magic Spring and fall etc, changed the earth in the filter, the water looks clear.
This makes no sense. Please help if you can. We are at our wits end.
