gunite pool 22x44 about 40k gallons SWCG.
took cover off to change lights and pool was green and brown and it was embedded into plaster. Never had it open this bad. Pool guy said he'd drain it to scrub it and basically start over.
Husband decided to drain most of the water and spray and scrub pool down with bleach. He shocked it then with power powder plus. Current CL levels are off the charts, well over 10. PH is 7.2. Water is basically just a few inches over shallow end, hard to get a correct reading... I do have the advanced test kit.
Problem is pool isn't yet open. No filter can run yet as water is so low. Do we fill and hope to clean bottom or what. Some of stains were in pool last year after we paid for a bad acid wash..... overall brownish/orange tinge though is upsetting.
After initial shocking and scrubbing for a few days and removing debris, now the water isn't green nor brown but a cloudy blue color on deep end. Looks clear on shallow end. the sides and bottom though are discolored and there is streaking on bottom. Pictures of pool gunite look whiter than pool actually is, lots of light brown/orange tinge.
Trying to decide do we fill it and start it up or drain it some more and try to acid wash it ourselves?
What is cheapest solutions?
Next to no hardness levels, salt levels deminimis. I didn't test for CYA.
Thanks so much for your help!!
