my little 300gal soft tub seems to be consuming a lot of bromine. I use the 2 part bromine solution when i want to boost the level and have a floater going the rest of the time. Last year I had the floater almost closed and was able to keep a 6ppm level of bromine, this year its almost wide open and I find I have to keep boosting the reserve with the 2 part solution more often, like every 3-4 days. Last year it was like once a month. The tub is being used a little more often this year but can that account for the increase in consumption... I currently use the MPS shock.
One thought... is there such thing as "expired" bromine tabs... I notice that the tabs don't smell as strong as the last batch. Could that be the reason why the floater doesn't seem to be working as good as before? and no, I don't make it a habit to sniff all my chemicals
