Should/Would algaecide PQ60 or yellowout work???
I had a house with a pool that and started maintaining last year and this year.
What I finally figure out by reading lots of posts and what I experience from last year and this year is I had mustard algae.
This time, I had mustard algae when I am maintaining FC @ 6-8 and CYA @ 40. I bought the TF-100 test kit this year.
I shock it to a bit over 20ppm of chlorine and I am seeing it growing more and getting cloudier over 3 days even with brushing and vacuuming.
and then I read more and finally realize it is mustard algae, I then shock it to 30ppm, but end it up with 43ppm with the test kit.
(not sure why, I used the pool calculator. but not important now)
run the filter and the water is crystal clear after about 36 hours.
but the problem is every time I shock to such a high level, I loose swim time at least a few days and it is always the prime times for swimming here in MA.
and this week and the next, the temp is around 90 and I am loosing swim time for at least a few days.
I just feel I am doing all this work for very little swim time..
I also added borax (probably about 20ppm. I know it should be at least 30ppm, but I don't want to to do until I have a test strips) to the pool now and hope it helps to prevent it.
I also see some green stuff on my garage roof, I wonder if that is where it is coming from, if so how do I get rid of that?
would putting PQ60 for maintenance work to prevent it?
or should I use yellowout when it happen be better?
