Contestants have just a few days left to submit their before-and-after photos for NC Brands' Amazing Pool Clean Up Contest.

People are asked to share photos and videos showing a pool before and after the clean-up to reveal the transformation.

First prize is $6,000; Second prize is $2,000; Third prize is $1,000.

The contest is open to pool/spa professionals and consumers who use one of a list of NC Brands products before shocking their pool with an EPA-registered chlorine that kills green or yellow algae. The contestant then must use one of the listed products to clean up dead algae.

The final day to enter the Amazing Pool Clean Up Contest is July 31, 2019.
