Get the shovel out buddy. We are due to receive up to 25cm of snow today. I'm guessing you cowboys will get some of it too.
Bromoblast is great. It replaces bromide & bromate and is both products in one. If you have bromate, you will need a 1/4 cup to shock. With Bromoblast, it is far more concentrated and a capful is lots! Use up your remaining bromate and continue on with bromoblast. Start with small quantities and test. Half a capful is lots just to increase your bromine 2 or 3 ppm. It's far less expensive in the long run and you are putting less product in the water keeping your TDS lower.
Your dealer should be able to give you a start-up & weekly maint. sheet on bromoblast.
