I just got my TF test kit this week and have performed my first test today.
I didn't realize my chlorine tower was empty, and I don't know what effect that will have on my results.
My first set of results are as follows
Total Alkalinity - 180
Ph is approx 7.8
Ca hardness is 800
CYA is 100
Could you please give me an idea of what products I'll need to add?
