Just purchased a house with a pool and I'm now trying to take care of it. The pool is Plaster pool ~25,000 gallons, kidney shaped with one skimmer and two drains. I believe that the filter is a DE. Also, it has a heater that currently doesn't work.
The previous owners had tablets in the skimmer and a float with about 6 tablets in it. I took those out after the first couple of days as I wasn't sure they were needed, plus I read that putting the tablets in the skimmer was a bad idea as it is very hard on equipment.
We have been cleaning it daily and taking measurements and recently took some water to the local pool store and received these results:
Free Chlorine 3.04 ppm
Total Chlorine 3.25 ppm
Combined Chlorine 0.21 ppm
Hardness 159 ppm
Alkalinity 43 ppm
Cyanuric Acid 34 ppm
Copper 1.22 ppm
Iron 0.06 ppm
The store advised us to add pH Up ~18 lbs. We added 16oz circulated the pump for a few hours and then the next day added 16 more oz and circulated the pump. The pH is now at 7.2.
The water is now cloudy and I think that the filter needs to be back-washed as its pressure has gone up about 10 psi.
Also, the sides of the pool are chalky and are turning it white. This can be washed off, but I'd like to correct the problem.
Should I keep floating the tabs all the time in the pool?
Do I need to shock the pool? (hasn't been shocked in a couple of weeks). We were thinking of back-washing the filter, cleaning the sides of the pool, and shocking tonight...good idea?
It seems as though I just have to wait for problems and then employ corrective action to correct them, isn't there a way just to keep status quo in the pool? Maybe some sort of routine?
Thanks for any and all help.
