I bought a Poolmaster test kit to compare with my Taylor kit. But my chlorine readings don't agree. Taylor reads too low and Poolmaster reads too high.
What should I believe? The pool looks ok now but I'd like to know why my chlorine readings are opposite are weird. The PH is ok and Alkalinity is also ok.
