I'm trying to help a friend through his first pool opening while explaining to him why BBB IS BEST. He started with soupy green water, which is now sort of a milky white. I took my kit over there today(Taylor K-2006). He's been adding bleach but the last was 2 175oz jugs two days ago. CL is .2 / pH is below 7/ When I put in the reagent for ALK, it should have turned green but instead was bright pink. It's a liner pool. I found the CYA to be about 150! I explained why the next step had to be drain and refill, possibly several times.
We're still trying to determine exactly how the pool was plumbed, as the factory valve labels are gone and nothing else is labeled. He thinks the volume is 30000gal but I think it's closer to 20000.

I know this is not that much to start with, but can anyone offer suggestions?
