Our pool water was just about black due to it not being winterized or covered correctly over the winter. I started attacking it on Monday after finally finishing the upgrade of my pool plumbing. Numbers/additions so far are listed below. I've seen some definite improvement in the water so far - it's now a mild brown color, and I can see maybe 6-8 inches down from the top before it's too murky - previously it was murky all the way to the top. Wondering if I'm generally on the right track and just need to keep up the attack, or if I need to modify my approach somewhere.
6/25 9:00am - pH 7.1, TA 150, CH 350, FC 0, CYA 0
-Added 18 oz of 6% bleach and 43 oz of 12.5% bleach (both old bottles from last year - which likely contributed to the very low FC reading 3 hrs later - probably much less than 6% and 12.5% after sitting that long)
6/25 12:15pm - FC 1.0
-Added 32 oz of 6% bleach and 32 oz of 12.5% bleach (I think these were from last year's bottles too, but don't recall for sure now)
6/25 6:35pm - FC 0.5, CC 2.0
-Hmm, just realized I missed logging the addition at this time - was likely ~44 oz of 12.5% bleach (new bottles from here on out)
6/26 12:30am - FC 2.5, CC 1.0
-Added 40 oz of 12.5% bleach
6/26 10:15am - FC 2.0, CC 3.0
-Added 44 oz of 12.5% bleach
6/26 9:20pm - FC 0.5, CC 1.5
-Added 52 oz of 12.5% bleach
6/27 7:40am - FC 0.5, CC 1.0
-Added 52 oz of 12.5% bleach
I didn't have any CYA in the pool until yesterday - I added what I had left from last year in a sock in front of the return, and it was pretty well dispersed by this morning. I need to get more today to get the level up to a readable amount. It's also been hot and mostly sunny every day this week which I know is eating up chlorine as well.
I've been targeting raising FC to 10 each time, and wondering if I should be going higher. Also whether the lack of CYA is going to hurt my efforts to get the water cleaned up, and if so, how much of a factor will that be? Thanks for any advice you can offer! We went on vacation last fall for a week with the pool uncovered and I never got it cleaned up when we got home, despite trying to SLAM it for a week or two. Really hoping to get a better result this time around. Feel like I must be missing something somewhere.
