I'll be closing on my new house in about a month. The house has a pool that will be open when we close. I just got my TF-100 test kit and plan on using the BBB method to care for my new pool. I'm planning on taking it with me when we close and testing the water. The problem is we'll only be at the new house for 2 days after closing before returning 8 hours to our current home. It'll be 3-4 weeks before we move to the new house for good.
There won't be anyone at the new house to care for the pool during the 3 week absence.
What should I do to the pool (water chemistry, etc -wise) to reduce the chances I'll be returning to a swamp when we get up to the house?
