We took off the leaf net last week. Clear water with debris on the bottom. These were the test results upon opening:
Cya was 0
PH was 7.2
TA was 80
We cleaned out the debris and shocked pool - brought it up to 10 ppm and held 24 hours. We added CYA and we have held chlorine between 5 and 10 ppm last several days. A couple days later we found this fine brown dust (algae?), which we have brushed and vacumned to waste 3 times. It is not slick, it is almost like silt. The day after each brushing and vacumning the brown stuff is all over the bottom and slanted sides of the pool again. The water is pretty clear and a light blue. When I sweep the junk, it clouds up the water. The pine tree pollen is awful now, but the sediment looks light brown/tan colored. The back wash looks yellow like the pollen.
I also have some stains on the fiber glass steps and liner that I plan to use ascorbic acid to remove. Which one of these should I tackle first? How do I go about it? Oh, btw, I put a quart of polyquat 60% in the pool yesterday.
My numbers are:
CC .5 ( maybe less)
What is Total hardness? And what should it be?
26000 g inground liner pool
Thanks for you help!
