Hello Matthew,
I am not a pool expert so I am not offering advice. But I can say that I too have a very high CYA (over 100). I've been battling persistent yellow algae on the sides of my pool since mid-May. Weekly brushings wouldn't remove it all, and it came back with a vengeance.
Last weekend I took the advice of members, including pooldv, and I added enough liquid chlorine to get my FC up to 40. For my situation it was 12 gallons, and I determined that via the calculator.
I can say that, for a week at least, it really worked. I did brush thoroughly today and there was some light yellow in places on the pool walls, but it came off so easy, and I believe it was dead and just needed to be swept well.
So now I will keep my FC up to 12 for the summer. For the week, I have been able to do that by adding 1 gallon of liquid chlorine every 48 hours.
For me, the calculator worked great, and the prescribed amount of liquid chlorine did the job. I am pretty happy. Oh, and I have NOT used pucks now for one year - my CYA is a holdover from three years of using just pucks. I found this site a year ago and haven't used them since. I we were not in a drought, I'd do a partial water replacement, but that is not possible in California at this time.
Good luck. Randy
