Back in mid August I reported on the Algae Bloom in the pond.  I’m now very pleased to report that the bloom is over and the pond is clear again.

It appears that the new UV light has done the trick.

This incident did give me an idea for a new product.  Since a UV bulb can continue to give off  visible light after it stops emitting UV rays, we need a simple inexpensive UV detector. It could be strips like ph paper or a meter like an amp meter.  The market is fish and pond supply stores but could also be worried moms and people at the beach.  Maybe super sensitive skin is the answer.
