Welcome to our forum.
I've tried both- granuals and tablets. Whit the granuals my bromine levels were too high, with the tablets a bit on the low side. I prefer the tablets and lower bromine readings. I throw in a tsp of di-chlor every other soak and my water has been crystal clear (so far!). What do you consider "normal" bromine levels? drprwnap
drprwnap...I still have cartridges but I'm planning to reuse them when my supply is gone. You're using the tablets...what is your bromine reading?
