Water in the pool!

We finally have the pool fully assembled and filled with water. TJ got in it before Bill was even done filling the pool. The water was COLD, but it was over 90 degrees outside that day, so TJ thought the water felt good. Now that the pool is completely filled, the saltwater system is functioning, and the water is clear, the temperature has cooled off significantly and no one wants to swim. We haven't hit 80 degrees in days, and the pool temperature is a chilly 63 degrees. Figures.
I hope the water (and the air) warm up soon! I'd like to try out our new pool and also work with TJ on learning how to do some basic swimming.
