We have a new Marquis Epic, I love it. Â The problem is I can't get the Bromine to show any reading. Â I set the Frog cartridge up to number 6 (highest) and I have the filtration running 4 hours a day. Â This is the inline system so this is why we up'd the filtration. Â 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. Â 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. Â Do we need to add bromine salts at fill up or some thing. Â I have been reading this forum for 3 months now and I love all the great advice. Â Thanks again.
