Opening pool with massive algea growth

I could do that.

Back with today's numbers. Last night after adding 3 Gals TC 19 CC 1 FC 18, This AM TC 14.5 CC 1 FC 13.5, Lost 4.5 ppm overnight. Pool is noticeably clearer today, the sediment that was stired up with brushing last night was the least amount yet. Its getting close to being finally cleaned up. I added 1 gals this am after I took the sample to keep the FC high during the day hopefully it helps.

Sounds like you are making progress. Try to keep your FC between 10 and 15 unless you are less worried about liner bleaching (I have a 10 year-old liner so bleaching isn't an issue to me--and it's hard to tell what is from my few "shocking times" that exceeded the Best Guess Chart's numbers....and what is from 10 years in the sun.

Back with today's numbers. Added 3 gals had TC 18.5 CC 1 FC 17.5 after the addition. This AM I had TC 14.5 CC 1 FC 13.5 Loss of 4 PPM overnight. Pool actually is looking good. Brushed again last night and still stiring up sediment in the deep end. Added an additional gal. this am after I pulled the sample in attempt to keep FC high during the day. Wish I could get rid of the CC.

Wish I could get rid of the CC.

Keep at it, and you will!

Update for today. The pool actually looks almost perfect now. The Chlorine loss overnight was only 1ppm (first time that has happened) Still have CC of 1ppm. Do I continue keeping the TC high till the CC is eliminated? I am assuming its safe to start adding my CYA now too?

[BigDave]

Yep, Maintain shock level for your CC until 1ppm FC loss overnight and > 0.5ppm CC then keep shock level for one more day for good measure.
Sure, go ahead and start adding stabilizer, how do you plan to add? most of us choose to put it in a stocking hung in front of a return.

[Watermom]

I added some to my pool the other day but instead of hanging the sock in front of the return, I laid the sock in the skimmer basket and kept the pump running until it was all dissolved.
