Which kit (TF-100, Taylor K-2006, Leslie's Chlorine FAS-DPD Service Test Kit or variants thereof) would be best for testing a pool (chlorine) and hot tub (bromine). I'd like to get one kit that will do a good job on both. Note I use well water to fill both. The well water is 'filtered' with a Triple-O ozinator - but proably still has some metals/hardness. I do notice that the PH rises when I add the well water to the pool so I get through quite a bit of muratic acid.
