09-06-2025It worked well...however, I think I should have gotten red. I used it on my hydronic system to locate a leak and the glue on the insulation around the hot water pipes also shows up as green under the UV light. A little confusing when you are looking for a leak and all the insulation appears to have a leak! Maybe first look at the system you are going to use the leak detection on with an UV light first and see if anything gives off a fluorescent color. THEN purchase the appropriate color UV dye. Good luck!

> 3 dayI put about a 1/4 of a gallon in a chilled water loop on a yacht to find leaks and this dye is easily detected and works great. The system has about a hundred gallons of water in it. I could have used less product. Easily cleans up if you spill a bit. Just rinse with water.

Greater than one weekWhen my sons truck began to have radiator fluid leak issues, we tried to find the problem area but there was so much gunk on the engine block, it was difficult to tell. We put some of this fluid in the radiator (dont need to use much) and started the truck, then used an inexpensive UV light to see where the leak was. Worked like a charm!

> 3 dayI purchased the dye to help find a leak in the pond and used according to directions pouring it into my pond after I shut off the waterfall as directed. With the water still, the dye did not move much and did not go towards the leak as it should have. Instead, the entire water was green as the dye and hopelessly useless. Now I got almost a gallon of dye and out $29.

> 3 dayUsed 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.
