Bromine behaviour

[nofa93]

Is it normal that when I add a larger than usual amount of bleach(8.25%) (10oz+) in my 440 gallon bromine tub, the water shows a heavy green tint for roughly 30-45 minutes? Is this just a sign of high bromine levels due to the reaction with the bleach? And if so, shouldn't it show longer?

Thanks

High bromine levels especially at lower pH will tint the water yellow (extremely high levels would be more toward orange). Green doesn't sound like bromine unless your spa surface is blue in which case yellow+blue = green. It may not last in color if bromine has something to react with in the spa.
