Hi. First off, I am not THE pool guy or even A pool guy or even a pool owner. I'm just trying to help my next door neighbor and am probably in over my head.
She's got an inground concrete pool that calcs to 28700 gallons. I don't remember the pump size but the filter I believe is a Triton II 100C sand filter I think. I'll verify this when I go back over later today. When she uncovered the pool this year she said it was a green mess. She's used up to 3 bags of Turboshock daily for 3-4 days plus placing (3) 3" Trichlor pucks in each of the two strainer baskets and replacing them when consumed.
Used the last of the trichlor she had last night. FC tested this mornig at 21.5. The water is blue but grayish cloudy. I have brushed, swept, vaccumed to waste, added to the filter, bought and used the Taylor2006 test kit and read a lot on this forum.
I need someone to look over the numbers, offer up why it shows no CYA with all of the pucks and turboshock added and help me clear this water.
This afternoon the last test a couple of hours ago:
I am aerating the water to increase the PH so I can add MA to lower the TA. I'm not sure on the best way to raise the CH and also, I don't want to get too many things going on at once until the water clears. It is greyish white cloudy with what looks like a lot of tiny particulates in the water, easily seen at night with a light.
As far as filtration, I have added socks to both skimmers, removed the top from the sand filter and stirred and poked down into the sand with a broomstick. I don't think it's possible to do that with a water hose because the equipment is in a pump room with a lot of electrical on the floor under the perimeter of the filter. The filter, when clean after backwashing runs 8 psi. I added DE until the pressure rose to 9-10 psi. I also pulled the filter pump and cleaned the impeller and replaced a bad O-ring on the end of the volute. The pool and equipment is all 5 years old.
any help on getting this pool cleared up and getting the water balanced is greatly welcomed. I've been over there daily for the last 5 days.... Right now I feel like the best thing I never did was put in a pool.
Oh, I also got a fish tank test kit, drop style, to test for ammonia, it showed none.
So have it, besides move, what do I need to do??
