I have a newly resurfaced/redone inground pool. I am located in central Florida just east of the Tampa Bay Area. Here are the specifics:

IG 12,500 gal (previously 'marcite' now 'Marquis' finish). I also have a solar system for the pool that is not in use yet and the pool is uncaged with approximately 9 hours of direct sunlight per day. I am filtering my pool in three hour increments twice per day from 6:00 AM to 9:00AM and from 6:00PM to 9:00PM. The reason for the late time is to keep the pool temp under 92F. Pool water is crystal clear. Originally filled with unfiltered county supplied (drinking water). STARITE DE filter (30 sqft) and a 1.5HP STARITE pump. All water lines to/from the pool are 2". I also have a Goldline Aqua Rite clorine generator (Turbo Cell).

Test Results:

FC: 2 ppm
CC: .5 ppm
TC: 2.5 ppm

TC (OTO): 2.5 ~ 3 ppm
PH (OTO): 7.8 ~ 8 ppm (high)
TA: 145 ppm (high)
Cal: 530 ppm (high)
Cya: 40 ppm
Salt: Aquarite Display = 4000 ppm (high)
Aquarite Instant = 3700 ppm (high)
Bens Salt Test: 5000 ppm (very high) I ran the test twice.

As you can see with the exception of the chlorine, everything else is high. I know that the only way to reduce the salt level is to partially drain the pool and refill with fresh H2O. This will also change the remainder of the test results.

However, my major problem right now is that the interior of the pool finish is very very rough. Enough that it causes excess wear on the feet that resulting in bleeding (kids feet, not my wife or I as we don't play as much in the pool). I think that this is caused by the high Calcium level which should be reduced when the pool is partially drained and refilled.

Questions:

How much water do I drain and replace to get the salt level down to the recommended 3200 ppm and which results should I use to calculate the amount? Bens or Aquarite?

How do I get rid of the high calcium levels?

What advice can you provide me to smooth the interior of the pool again, brushing with a steel brush, increace the acid level to re-etch the pool, another method, or a combination of the above?

I am sorry for the long post and appreciate any help that can be provided.

TIA
