Thanks for the interest in my ongoing pool transformation. When I read your question I thought to myself.....that is a good question. I have not even checked the temp. Does the water temp affect the SLAM process? I am going out of town for a short trip. Leaving this afternoon, and will be home Sunday afternoon / evening. So my plan is to make sure everything is good, and still at Slam level before I leave. I will throw the thermometer in today, and let you know the temp. along with my other test results. I was not able to check anything this morning as it was pouring rain when I left for work. I do have the robot in the pool set on the auto cycle for everyday so it should make a pass while I am at work.
