I'm new to maintaining a hot tub. I've also built the top myself, which was a it's own journey and a story for another time.
I sanitize with granulated bromine, and some slow dissolve bromine tablets in a floater. My pH is in spec.
I've shocked my tub with a non-chlorine shock three times since I got it back up and running a few weeks ago. I'm shocking based on the product advice, which says to apply it every 5 to 7 days. When I apply the shock, the brome levels test very high for a few hours. I test with a Taylor hit. I understand the initial high reading to be normal. What happens next, I don't know what to make of. For about a day, sometimes more, the test will indicate total bromine to be at the highest level which is 10-20ppm. Sometimes the color even looks darker than the scale. Then after a few seconds the test sample will lighten up and then stabilize.
Which reading do I trust? Do I trust the reading immediately after adding the reagents and mixing the sample, or the one after a few seconds pass? Is it possible I don't need to add as much shock as the instructions say? Do I not need to shock at all, or perhaps adjust my sanitization schedule and method?
