Concentrated Red Tracer Dye - Highly Concentrated Fluorescent Water Tracing & Leak Detection Dye - One Gallon (128 Ounces)

It works just like they said

If tracking sewage gets you moist, this is the dye for you. I also got the blacklight flashlight and that worked well, too.

OK product

Everything was good

Good product

I did not have any dislikes about the product

Worked very well to find 2 water leaks.

Used to locate leak in in-ground terracotta sewage piping.. Worked great.. Probably used a lot more dye than I needed too, but nonetheless it did its job..

DID THE JOB

Too biodegradable...dissolved within hours...did not trace the leak in a concrete lagoon
