Natural WaterscapesPond Dye - Vivid Blue Super Concentrate - 1 Quart Treats 1 Acre up to 6 Feet Deep, True Blue Pond Dye, Creates Vibrant Blue Color in Pond Water

This is supposed to turn your pond blue but it just turned it green and it looked like an algae infested pond. Not worth the price. Keep looking there is probably another brand out there that works.

This was supposed to last for a month for 1 acre at 6' deep. I have 1/2 acre going from 3-8' and the die didn't last 2 weeks. It rain twice in this time with not much accumulation so I'm not sure why it didn't last closer to a month.

Amazing color very vibrant and long lasting...happy with this purchase, will be buying again :)

It dud not change my pond blue. Do I need to put something in for the algie? You cannot see it only green muck on top of the pond.

Initially I was upset because I thought that I was going to get a gallon of dye, my mistake. I've ise other dyes, but this stuff works better and lasts longer. I don't know how it's made, but this stuff is potent!! I'll get more when I'm ready. Great product.

The bluing is amazing. It does not take much, but it will stain your skin. Wear gloves!!!

Great product. Works very well on our pond. Seller even personalized not only the paperwork, but the packaging as well.

I have a 1/3 acre pond that is an average of 5' deep and figured 1 quart used as directed would be sufficient so I purchased this product. I disagree with this label as my pond has a very light blue tint that of a pool with a painted bottom. Would not recommend for anyone with a pond larger than 1/4 an acre.
