Green Tracing Dye - Highly Visible Concentrated Fluorescent Leak Detection Dye - 1 Gallon

Worked great was able to find the leak, saved my dad a new liner. Leaking thru the skimmer gasket.

This stuff works fantastic. We used it to find a anti-freeze leak. We tested pressure tested the system saw nothing. We put in about a 1/8 of a cup of this dye started the engine and within 30 seconds the seal at the top of the radiator turned green.

I used this in a Halloween prop to make a bio hazard liquid, Product worked very well, made a great contrast in color especially adding a black light.I used a 1/2 a cup to 5 gallons of water which was excellent.1 gallon will last several Halloweens.

Surprised how well just a bit worked. Clearly visible.

This stuff actually works. I just wish it would come in a smaller overall amount. We didn’t use that much of it to figure things out. And I have a whole lot left over.😉

Perfect dye for leak detection or other creative uses. A little goes a very long way, so use it sparingly, but there's no better product for dye tracing! The dilution instructions on the bottle are easy to read, and the brightness of the dye is surprisingly strong. Easy to use, but will stain any clothing, so be very careful.

This product worked perfectly to help identify pipes and the flow of water to the back of the yard. The color is nice and bright so easy to identify. It was easy to use and a good value.

Dyed my hands yellow, my pants yellow, everything it spilled do yellow. Definitely wear you're PPE if you don't want to be a yellow color. But as soon as it hit the water it turned into a bright neon green that I had no trouble seeing on a sunny day. Sadly I did not find the leak in my pond but that is at no fault of this product. A+ product.
