Hello everyone.
I’ll give a bit of background quick
Outdoor fiberglass
15,000-20,000 gallons
SWG
Use a solar cover most of the time.
In Virginia Beach
-just tested my pool water and I’m stumped
Took a sample of the shallow end next to an output and the deep end
These levels came out the same
Alkalinity 60
Cyanuric Acid 60
Calcium Hardness 150
Ph 7.7
But deep end was
FC-10
TC-5
CC-5
Shallow end was
FC-10
TC-10
CC-0
Ideally I would like to raise my hardness and CYA but I’m concerned with my chlorine levels.
Thanks
