Blue Lake and Pond Dye - 1 Gallon

Brilliant, lasting color in my pond. I use it at about one quart per 30,000 gallons. It lasts for several months and only needs replenished after overflow events.

So far it's changed my pond water to a pretty light blue. The real test is how long it lasts and if it is strong enough to keep algae from growing. I will let you know how it does as it starts getting hotter and how long the color holds. I usually put in two gallons every three months when it's hot. If I have to put extra in it's ok as this product is much less expensive and Han what I usually purchase at a chemical supply store.

I have used Blue Lake Pond Dry several times; I absolutely love it. Now that I live on land with a pond, I will be using quite often.

Poured it in our pond gradually riding in a paddle boat %26 after the wind blew it around a little it looks great!!

Poured it around the edge of the pond and in a few hours the color had spread through out the entire pond. Couldn't be easier.

We have used this in our pond for years. It makes it a really pretty blue color. The amount we use makes it look a natural blue color, but not fake looking. It does not hurt fish or wildlife. It keeps lily pads and algae at bay.

Packaged well and it seems to keep the pond stabile. Pricing competitive.

It worked just like it was said to work was cheaper than any where else considering it shipped free will buy it again

It spread out though out the entire pond with even color in shallow and deep water

Good color fast shipping
