hi all,
i've been trying to wrap my mind around a question about maintaining FC, and i just can't decide which side to take. let's say there are two pools:
pool A has 30 PPM CYA and needs about 3 PPM FC.
pool B has 60 PPM CYA and needs about 5 PPM FC.
here's the question: will pool B actually use more chlorine overall? in other words, if both pools are the same size and both are at their suggested PPM for FC, would they require the exact same amount of chlorine added to maintain those levels? i always kind of figured keeping a higher FC requires more bleach, and more expense. but when i put it this way, it seems like it would require about the same?
