Mustard Algae

[tnalaskan]

I did have just enough of the reagent for 1 more test. The FC is at 40 again. Why is it dropping so fast? I will add 7 jugs of the 182oz 6% bleach, which is what the calculator says to add. (6.8 jugs) It is very sunny here today. Should I add an extra jug for good measure?

I added the 8 jugs of bleach directly to the pool water instead of through the skimmer as we had been doing. Poured in the areas where the brown spots were. They imediately disappeared. Praying they will stay gone! Thanks so much to everyone for your help. Do you think adding polyquat would be a good idea or not? My ph is only around 7.2 Can I add borax while dealing with the algae issue?
