After two year of using the BBB method and strictly liquid bleach, I have never been more troublefree in my 18x36 vinyl inground pool. However, this DOES take daily attention. What if all your CA, CYA, etc. parameters are right in the desired range and you go away on vacation for a week? I usually add a half gallon 6% liquid chlorine a day, and have had my neighbor follow up with a gallon every other day in the past, when we were away a few days. But, for a whole week? Any advice on how to use lithium hypo as a fill in for a week away without imposing that much on your neighbor?
