Green Water Tracing & Leak Detection Flourescent Dye - 1 Gallon

Used this to find a leak in a sewer pipe. This stuff is super bright with a black light even in direct sunlight. Made finding the leak a breeze.

Does it work? Yes! Repeat customer here. If you want to see the flow at night, buy the recommended UV or blacklight flashlight. It does work! I already wrote a review for the first jug. See that also. We shared our first jug with neighbors, so got another one. It is not green in the jug, but dont be alarmed. It will Glow green. Daytime its a bright neon green. Nightime, use the flashlight I recommended above. Please note, it did stain our stamped concrete patio a little, but was worth it to find the stormwater runoff from uphill neighbor who re-graded the yard. Now the City is involved. Needed that proof.. green dye doesnt lie :)

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.

works

Looks orange but will turn green when mixed with water

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.

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

This product worked perfectly for exactly what its intended to do. We used it to test the effectiveness of our septic system. It was shipped in a timely manor and service was great. It did arrive with a crack in the lid, but there was no leak, and since it was packaged in plastic it wouldnt have been too messy if it did leak. Overall were satisfied! Thanks!

Great price and it did the job. Cheaper than a plumber!

Very distinctive green glow. Powerful tracing tool.
