I have the following parameters established:
1. Shading net over the entire pool area
2. Opaque pool cover (at night and most of the time the pool is not in use)
3. A working Liquidator
4. 2 x 200gr Trichlor pucks already dissolved (approx. 15 ppm CYA according to the pool calculator)
According to the (amazing) FC/CYA table, my target FC should be approx. 1.8 (with a suggested minimum of 2 my target is actually 2) which is where I manage to keep it thanks to the (excellent!) Liquidator, the CYA, and the shading net.
My water is clear and clean
I was wondering though - the comment at the bottom of the table states that FC is more effective at lower pH, and I remember that the higher the pH, the less effective FC is.
My age old problem of rising pH seems to be a lot simpler to manage if I allow the pH to remain in the area of 7.5 instead of targeting 7.2.
How does that affect the effectiveness of FC and should I have a different target than what the FC/CYA table suggests? (given that my pH is usually around 7.4-7.5)
Come to think of it, are the values in the table given for a specific pH?
If so, how do I adjust them given other pH values?
