AirmaxTwilight Blue Pond Dye 4X Concentrate for Outdoor Ponds & Lakes, Natural Pond Colorant & Beauty Enhancer, Block Ultraviolet Rays, Fish, Bird & Livestock Safe, Easy Liquid Application,1 Quart

We have used this product from day one in our pond. We get so many compliments on how pretty our pond is. We love the twilight blue!

Product seems hit or miss, I've dosed the pond and it's worked great, then dosed the pond later in the year with no effect. This no effect thing has happened twice now. The water levels are lower later in the year so there has to be an issue with the product.

The media could not be loaded.  I use this for 1/4 acre pond. It says it treats 1 acre 4'-6' deep. Mine is 5'-11' at its deepest, so a half bottle should do it. I use a full bottle and I end up with a greenish tint. I hope for a darker more natural color. It does look better through the camera than in real life

Don’t put this is and then get 4 inches of rain when you have had a serious drought. I will try it again in July. Lol. It did change the color of my large clay pit lake which is deep in places. I just wish it had lasted longer than a week.

Love it

Only downside is you have to be very careful not to spill. Will stain skin, but comes off in a couple of days. Use disposable rubber gloves. Putting cap back on is easy, but again, watch out for a spill. I do everything over a laid out plastic kitchen bad, with gloves, and make sure don't have to go over pavers etc. But the result is worth it.

I've used various pond dyes over the years and have never had a dye that turned out colorless. There is no blue color to my pond at all. Now I'll have to buy a different dye from someone else. Very DISAPPOINTED!

This product is part of my pond maintenance routine. I put it in monthly. It’s concentrated, so I only need one for a 1-acre pond. It diffuses the light to avoid algae growth. There are four colors to choose from, but Nature’s Blue is my favorite. It has a nice blue color. Use this product along with Airmax Muck Away, and Airmax Pond Clear.

Turns water very dark almost black. I have a 5000 gallon pond and only had to use about 50 ml to see nearly immediate results.

I have used this product for a couple of years and it really works well to get rid of the algae. We have a large, deep pond and it protects the fish from the herons as well. The water has a nice deep blue color. It was delivered on time with no problems.

Very little goes a long way. Great product.
