We opened the pool on 5/9 and put algaeside in it bc it looked like a swamp. Then we shocked for about 5 days Granular 56. At this point we could see the bottom in shallow end but not deep end. Phosphates measured around 500 so we put in a bottle of phos remover. Got better. Again, can still see the bottom of shallow end but deep end (8ft deep) is solid dark teal/green to the drain. The sides are slightly visible and I can see what to brush. Phos is barely blue now so we shocked this morning with Granular 56.
We are considering to floc tonight but before we do I wanted to get advice from this forum. I've read many threads but am still confused. I've seen the ABC's of pool chemistry, the shocking procedure, etc.
Here's are numbers as of this morning. Our pool is 32,000 gallons, inground vinyl liner, and we live in Central Illinois (around many farm fields).
300 - cal hardness
3 - chlorine
0 - free chlorine
6.8 - PH
10-20 - cya
Would appreciate any advice before tonight when we do more.
Oh I should ad that the pool store said to put phosphate remover in until it's clear or chlorine won't hold. Then another pool person said to disregard that. I'm so confused.
