Airmax Pond Dye Packets Nature's Blue Colorant for Large Pond & Lake, Beneficial UV Blocking Color Concentrate, Maintain Clean & Clear Water, Fish Safe, Easy Treatment, 2 Soluble Packets

Have a 3 acre pond, and use this to help keep pond clear of unwanted growth. We are and have been very happy with this product

Works well, color is very nice. We have approx. 100,000 gallons and if I could go back, I would only use one pack for a slight tint. So, before you throw two packs in, try one a wait a day or too. Wear gloves, this stuff takes days to get off your hands. No problems with the fish.

I love these packets because I don't need to worry about getting dye on my hands; I just toss a packet in once a month. This product helps keep underwater pond weeds from growing out of control by blocking some of the sunlight, and as a bonus, the color looks really pretty!

Works well. Easy to use

very good

This is the best product we have used in our pond. Tried the liquid but you can see that trying to walk around the pond is difficult. After a heavy rain the pond has a muddy look. I toss two packs of dye into the pond and the next morning we have a great looking Blue pond. It does not affect the Catfish, Perch or Bass. The Turtles are happy with it also. Highly recommend this product.

I wrote a bad review on packaging before but decided to try product again because I like the way the product works in the pond (Once you get it In The Pond!!). The blue dye still reappears on garage floor from leakage after opening outer bag months ago.This time I opened the new outer bag next to the pond but blue powder again shows up on pants, shoes, grass, etc. because of broken inner bag again.It shouldn’t be that difficult to package powder better.

The blue dye works well on our pond.
