How do I switch over to the BBB method if I have been using Potassium Mono****. Do I have to wait a specific amount of time, or do I go by water testing Can I use both methods? I have purchased the recommended test kit TF-100. I have been using 2lbs of the mono weekly, pool is 20,000 inground vinyl liner. I cant wait to use the BBB method.
thanks
