Sapphire Blue Lake & Pond Colorant - 1 Gallon - Deep Dark Blue Color Treats up to 1 Acre - Combination of Crystal Blue & Blackout Pond Dye- Environmentally Friendly Pond Dye

this product works well and lasts about 2 - 3 months for our 3/4 acre pond

The media could not be loaded. This was my first time using pond dye. Tried it first on my small 1/3 acre pond first just to see how it worked. Worked really well. The water has always been muddy and this spread thru all the water in a couple of hours. Water is beautiful now. Used about 1/2 gallon since I have depths of 5-15 feet deep. I’ll be buying more to do my 3 acre pond. I’m not sure how long it lasts but application, color, how fast it worked, and the price were all very good. My ducks swam right thru it before it spread and they didn’t turn blue. I could also start to see deeper in the water so I guess it’s actually clarifying the water as well. Definitely recommend this product.

Always works - repeat user;

This does what it is supposed to do. It is very good for the health and beauty of your ponds.

We just built a new pond and there is not much shade around due to the digging process. The dye seems to really help keep the algae down to a minimum even though the pond is in full sun most of the day. It is supposed to help with keeping the water temperature down as well keeping the fish healthier. I have seen other ponds in the area covered in algae so this dye must be doing a decent job. The color is nice and gives it more of a brackish water look.

We use this in the pond on our property with catfish and perch in it. It helps them hid from Herons looking for food, aesthetically it looks so much nicer than brown/muddy water and is safe for the fish, ducks, etc that use our pond as a water source.

It made our pond a pretty blue, yet it still looked natural. It is the best of all the colors we have tried.

Great product and a lot less expensive
