Recently switched to bromine since my swim spa can sit unused for up to a week while traveling. Was using MPS as an oxidizer but recently switched to bleach. Trying to calculate how much bleach to use to raise bromine levels. I know that I calculate bromine levels by calculating my free chlorine results by 2.25, but how do I convert the amount of chlorine to add to raise bromine levels.
For example, for my 1500 gallon swim spa, pool math tells me 2.2 oz of 8.25% bleach will raise my free chlorine level by 1. Should I expect my bromine level to go up by 1, or 2.25, or some other number?
Thanks.
