When I check my FC, it is the same anywhere in the pool I test. My ph ranges from 7.2-8.0 depending on where in the pool I take it. In both cases I use a water sample 18" from the surface.
Is this usual?

Absolutely not. If the water is circulating correctly in your pool, ALL chemistry should be almost identical regardless from where you take the sample.Is this usual?
