I have a very minor mustard algae presence in my pool. What I mean by this is that it is mostly clear, but there are a few spots, namely on the plaster right under the rock water fall, on tile inside skimmer gutters, along some grout corners on the water line tile, and in the spa which has a constant spill over. I don't lose much FC day-to-day, and I simply brush the pool to get rid of it. It comes back over the course of a week or 2 if I don't brush regularly.
Here are my questions:
1) If I truly get rid of the Algae using the Mustard Shock levels and maintain that until no FC loss over night, will it stay gone as long as the FC level does not drop back down.
2) Will this small amount of algae regularly appear even in a perfectly maintained pool when conditions are ripe and things like brushing are not done frequently.
3) If I do in fact need to get rid of this algae once and for all, my plan has been to wait until after the summer sun dies down a bit and I get more shade on the pool. My thinking is that it's easier to maintain the high FC level when I'm not losing 4-5 ppm each day to the sun alone. My concern, however, is how easily will I get my level back down to a point where I can use the pool and hot tub if it's the winter month and my FC loss each day is minimal with all the algae gone? In other words, will I be stuck with FC at 24 from November through March without the sun to burn it off?
Thanks for your help,
