Took the cover off this weekend to find algae growing on the floors and walls. First time I haven't opened a clear pool since we had it installed. Oh well, guess it was bound to happen. I actually think the growth may be from last year after closing. The water is pretty clear, I can easily see to the bottom of the pool and samples are clear. Water temp is around 50-54 degrees so algae shouldn't be growing.
Now for the question. Checked CYA and I'm at about 20 (maybe a little less). Based on this my shock level is only about 10. I am going to initially hit it with bags of shock rather than a bunch of bleach. I'm thinking the bags of shock will boost the CYA to a more appropriate level while hammering the algae. Does anyone have any idea on average how much of a CYA boost I can expect to see?
Thanks,
Rob
