We'll be gone for a three days this week, I don't know if I will be able to get anyone to dose the pool with chlorine during that time. I don't have any trichlor pucks. I was thinking of dropping some MA (need to get my TA down a bit) and get my pH to about a 7.0 and get the chlorine to SLAM levels. I lose about half my chlorine every day, but I do have the heater running. Wont be running while I am gone, I'm thinking that should be ok for a few days?
