I converted to BBB a few years back, and my pool has been crystal clear since. Starting last season, I basically reduced my testing to chlorine and CYA only - ignoring pH levels. I have a 15' AGP in NJ and the pH level just doesn't fluctuate. So although my test kit has a bunch of different bottles, I only use the R0001, R0002 and R0013 re-agents. If my pool remains clear with only testing Cl daily and CYA monthly, is there any reason to bother with the other tests? Is it just my location and type/size pool that allow me to get away with this? Thanks.
