We have a new Marquis Epic, I love it. The problem is I can't get the Bromine to show any reading. I set the Frog cartridge up to number 6 (highest) and I have the filtration running 4 hours a day. This is the inline system so this is why we up'd the filtration. My husband tried shoching with 1 oz of dichlor last Saturday, the chlorine reading went to 4 ppm and the bromine reading went to 5 ppm. Well the next night, we had an 8 hour power outage and then last Monday afternoon, we had a fire on the side of our house, lots of damage to exterior of house and no power for 53 hours again. Do we need to add bromine salts at fill up or some thing. I have been reading this forum for 3 months now and I love all the great advice. Thanks again.
