Night Blue Lake and Pond Dye - One Gallon of Professional Lake & Pond Dye - Treats Up to 1 Acre - Combination of Pond Champs Blue & Black Dye - Safe for Fish, Wildlife, Pets & Children

I have used this product before as it doesn’t hurt the fish in my ponds, I actually have 2 ponds. I usually put it in the ponds 2 or 3 times a year as it helps control the pond scum. It does change the color of the water to a dark blue. As always prime shipping is the way to go as I know when I place an order that it will be delivered on time.

This product does a fantastic job of coloring your pond water. Directions are easy to follow and it works immediately. I would buy this again.

Love this blue color!

I live in E. TX where the silt is so fine, pond water never settles clear. Typically I use blue dye. The blue doesn't look natural to me and will turn into a pea soup color after awhile. I started adding black to it and it not only looks more natural but the color holds better. Black is harder to find, more expensive and not as strong of a pigment but you don't have to add much of it to blue.This looked great when I added it, the next day when it all settled in, the pigment was very weak. My pond was down 2.5 feet when I dyed. A full gal of blue would have been overkill. Typically I'll dump 1/2 - 3/4 of a gal in and safe the rest to top it off once it rains and fills up more. A full gal., no rain and a gal. didn't cover correctly.For reference, my pond is an odd shape, almost like a dog bone, when full it's roughly 70' x 40' at it's widest points. Call it an 1/8th of an acre? Deepest points might be 7', pond was down 2.5' at the time so call it 65 ft x 35' and max 4.5' deep.If you are just doing a small coy pond that has clear water, you might like this. If you are accustomed to dying ponds, you will be disappointed with this.

Best dye I tried so far. I did not want to do a sapphire blue so I kept using black, but it did not last. Not sure why. This is the first dye that lasted longer. Still not black, but not sapphire either, compromise.

Nice dark blue color with high reflective qualities!!

I purchased this product for my farm pond after having a less than favorable experience with a competing dye. This product has lasted over 30 days so far and continues to work well. I am very pleased.

I have a small pond so a little bit goes a long way!
