temp drops from 82 to about 79-80. no big deal...

By adding a sudden influx of cooler water you are also enriching the rays environment. I have had no problems with water changes that approach a drop of 10 degrees. If you have a larger system the rays have a chance to find a "warm" little corner to hide in until the water warms back up. You may actually notice some rays seeking out the source of the "cold" water and swim in and out of it's path.
