Are you recommending to drain my pool all the way? This was my original idea, but i am not sure if I can do it. I live less than 1 mile from the bay. I think I might be to close to the water column. I will be digging a hole today, to see if I will reach the column or not. If I hit water, it is my understanding that if I drain, it could collapse the gunite? Is this correct?

If I drain, I need to pipe the water about 200 yards, to a nearby sewer head. Have any suggestions on where to get a pipe of that size?

2. You suggest to add the dichlor to add free chlorine and stabilizer. What levels do i want my pool at? How do i calculate to get the ppm? Is this what the test is for? Is that the ratio of chemical to 1 million gallons? How much would you start with? i have a 7k gallon pool?

If I cannot drain my pool all the way down and start over, how would you do it?

Again, thanks for the help.
