Hi, we recently bought the house with the unground pool on property. We decided to open it in May. From the previous owner we learned that pool was not opened for last 3 years. When opened, there was a lot of leaves in it, so while working on pump/filter issues we clean up as much as we could. Few things were done: we change the pump to new one, as the old one was leaking, the chlorinator and the filter were changed as well. Now we have sand filter. The swimming pool is ~18,000 gallons.
The bottom was vacuumed at least twice, with a lot of debris removed.
Last Wednesday, (6/28) after we knew all is working we added 15 gallons of liquid chlorine, water from green changed to grey/brownish Filter is backwashed ~ 2x/24 hours since that day. On Monday (7/3) we added additional 10 gallons of chlorine, as the water did not improve (still very cloudy, color did not change). We just purchased the kit recommended to measure water parameters at home (didn't arrive yet), so we used our local pool store to check the water (last Friday): chlorine was very high (I still can't measure that with my small home kit, as is still above 5); pH ~7.2; alkalinity ~80 ppm, CYA ~6. Calcium was adjusted as it was 0 at that time, but I don't know what is now, as we didn't measure it yet. We have some stabilizer to increase CYA as well, but we were told not to do that until the chlorine is in range.
My biggest concern is how the water looks after a week: very cloudy, brownings/ grayish, we can't see more than 2 steps down. I know that sand filter is slower that the other but concerning is that there is not much going on and water is still cloudy and not improving. Am I just impatient? How long it will take to clarify the water? Should we keep shocking with chlorine or it does take some time now to filter the water? Should we add the CYA now or wait until the water is clear and chlorine in range? The pictures with water attached.
Any advices will be highly appreciated
