Awesome! Thanks for the detailed reply. Once I have completed some of the tasks assigned I will let you know how it is turning out.

pH has already been raised to 7.5 per the instructions in the PoolSolutions Guides. Do I drop it back down to your recommended levels? Pool is just being opened now (long story that has nothing to do with water chemistry. Yes I know it is late in the season ).

I have already dumped 4lbs of 85% powder shock in and the FC was at 0 in less than 24 hours. I also added one bottle of the Pool Frog Algicide.

I am going under the assumption that the CYA has all biodegraded since the FC disappeared in less than 24 hours and Pool Frog Bac Pacs use stabilized cholorine. So I am in the process of stabilizing per what I read in the PoolSolution Guides.

TL;DR I just opened the thing. Does that change your advice?

Thanks a ton and rock on.
