I suppose everyone heard about the devastating Brisbane Floods http://tinyurl.com/4dxfkk8. Fortunately where we live was not flooded, but many homes (let alone pools) in low lying areas were inundated with muddy water and will take a lot of work to recover.
However, while we were free of inundation the exceptionally intense La Nina weather pattern has caused very heavy rainfall over most of Eastern Australia this summer and the pool chemistry has suffered. I finally got back to is yesterday and found, among other things FC = 0, CYA = 0.
I added required chemicals and today's test comes up with:
FC = 5+
TC = 5+
pH = 7.4
TA = 50
CH = 90
CYA = 30
Temp = 26C (OK, well it is summer here)
My overall balance calculation comes up with 10.4 against a target of 11.0 - 11.2
I'd appreciate advice on how best to improve the balance.
