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

Works great! Pretty color and easy to use.

Keep that UV from hitting the bottom to curb algae growth. My pond is about 50ftx 250ftx6ft deep and half a jug will take care of it. Seems to last about 3 months per dose.

We haven't used any pond dye in a few years and I was tired of the brown water. It hasn't even been 24 hours yet and the pond looks so nice. You can really see my ducks and geese now. Would highly recommend!

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.

This stuff is great for helping keep down growth in a pond. My neighbors pond was covered in growth last year and ours stayed clear. It didn't effect the frogs or fish that I can tell.

great product at a fair price

Exactly what we needed and in the amount desired! Our pond is looking great already!

I absolutely love it today is day 3 after application and I could not be more pleased! One thing to note, I highly recommend using gloves during the application. My hands were covered in blue dye. I must say, as the instructions state I was able to successfully get it cleaned up by using soapy bleach water. I will certainly buy again.

PARA DARLE COLOR A LOS LAGOS Y PARA QUE SE VEA MENOS LA CONTAMINACION POR TIERRA Y HOJAS EN LOS LAGOS

Very good stuff thanks for the delivery I will be buying from you guys again

Thank you to the folks at Rainy River. The product shipment was delayed and Amazon said to get a refund. So, we requested a refund. Rainy River processed it immediately. However, our product did finally arrive, we received it and then used it. We advised Rainy River that it did end up coming and to please charge us. They declined and said please accept it as our gift, with apologies on the delay. We are so very grateful to them. We also wanted to share us adding just about 5-10mL of this product to one of our areas - and you can see the immediate change! Great product and great folks at Rainy River. Thank you!

The pond use to be yellow mud puddle look. Now it's a beautiful blue/green. We can see the tadpoles and turtles clearer.
