Tropical Ohio

We were told that using "pond dye" would tint our pond water a lovely color, plus interfere with the sunlight, thus retarding the growth of algae. This would be a good thing, as we have been doing weekly algae harvests. We put in less than recommended, and still got this vibrant blue green color in the water. Dear husband thinks it's a little too fake, but I love it! I asked if it came in any other colors, like fuschia or violet, or maybe even lime green. Dear husband was not amused. Isn't it pretty? (Now if the grass would green up, just think how it would look!)
