I followed the instructions to kill off the algae in my pool. Very successful.
After 3 days the pool is very clear, looks great.
My test numbers are making my head spin...
FC 7.0 - This is expected as FC was very high to fight Algae
CC < .5
Ph 7.0 - This is low, so I know I need to raise it
Alk 140 - This is high so I know I need to lower it
CYA 0 - This is very low, so I know I need to raise it
I read all the pool school articles. I am just not sure what my priority should be with these numbers.
Using the pool calculator I could put Ph down in to lower my Alk to 120, but this would lower Ph too, I need to raise my Ph.
I don't have a steady Ph raise, nor high calcium so maybe lowering Alk of 140 shouldn't be my priority.
I need to raise CYA, maybe using dichlor over 4 days as pool school suggests.
I have some trichlor tabs on hand (2) It may take longer but maybe just adding them to a floater will help.
The pool gets direct sunlight about 4 hrs a day, and I use a solar cover.
Thanks in advance
