Blue Lake and Pond Dye - One Gallon of Professional Lake & Pond Dye - Treats Up to 1 Acre - Royal Blue Color - Safe for Fish, Wildlife, Pets & Children

It made my mud puddle colored pond a beautiful blue. My pond is 1 acre in size so I used the entire jug. It was a bit windy the day I applied it and the whole pond was blue in less than 24 hrs. The stuff works great! It does what it supposed to do. Make sure to wear protective gloves as I'm sure this stuff will quickly stain anything it contacts.

Makes pond look great. Water much clearer

Great Product works great

UPDATE: after posting the below review customer service reached out and offered to send me another thing of dye to try. It took more than anticipated, but it did get my pond to a very pretty color. I appreciate this company standing behind their product and helping me to troubleshoot. I’ll purchase again and just know that I need to dose heavy the very first time (but use less to maintain the color)We have previously used the AirMax dye, but wanted to try something else. This was not nearly as good. It took a lot to get a similar color and the color only lasted a short while even in cooler temps. Would not repurchase.

Wonderful color and holds algae down and looks beautiful

Packaging. 1 gallon jug in a bag leaked onto my concrete step.Follow up: The company reached out and helped find a solution.

Excellent product
