Green Water Tracing & Leak Detection Flourescent Dye - 1 Gallon

It works...I guess. I used this to try and find a leak in my septic system. I even bought a UV light and thought I saw some. Turns out it was just the UV light in the water. I would try red to show up better in the yard.

I am unsure where my previous review went, however here is an update: When I received the item the color of the dye was orange. The label is as pictured but the color of the dye in the bottle is definitely orange. It will also stain your clothes that color of orange. After pouring the orange liquid into your drains and dissolving/mixing it with water it will turn the brightest green you have ever seen. I used it to test flows for french as well as finding downspout drains. Works excellently! Will buy again. Seller is top notch!

Thank you!

Do you need two gallons? No... Not unless youre trying to turn a whole lake green. Woooooow is this stuff bright

This stuff is brilliant--in more ways than one! Its super concentrated and super visible, and allowed me to sort out the bizarre drainage system on the property I recently purchased. Im totally satisfied.

Found the tub leak, wasnt anywhere near where I thought it was. This contrast lead me to the culprit

It worked fine with the low light (or UV light).

I used this green tracing dye to dye our 5,000 gallon fountain green for St. Patricks Day since I read this is what they use at the white house fountains since it wont stain the stone in the fountain. It worked great. It took about 1/3 of a gallon for the fountain to turn fluorescent green (see picture). Day two and it still looks the same with no stains to the stone.

We tried this in our man-made pond to find a leak. We didnt find the leak, its just too small we think. But we sure have green water. The pond has been green for about 4 days now. The fish and salamanders dont seem to be affected. Note: a little goes a long way.

Saved me from paying for septic dye test
