The next time you walk out to the backyard and notice the swimming pool has turned green, fire your pool guy, and then get yourself the new AquaVizor.

This cool piece of pool tech, announced today from AqualabZ, uses a sensor that tethers to the side of your pool and continuously analyzes the chemical balance of the water. It transmits information wirelessly to a display monitor in your home, telling you if your pool is ok, or needs attention. Should it need attention, the AquaVizor will tell you how much sanitizer to add.

It'll also tell you the water temperature, which ought to come in handy when waiting for the spa to heat up.

The AquaVizor is pretty much ready to use out of the box, except for having to enter some specifics about your pool's dimensions and type of sanitizer used.

Actually, how about this thing sending you a text-message when the water gets out of whack?
