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

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

It did exactly what I needed to see the problem coming from my neighbors property. Fast shipping! Disappeared completely..no residue.

Good product

Used it to find a leak in the hot tub. Got me into the exact place just like I hoped.

It works just like they said

Worked great!! Saved me from a potential legal battle with neighbor.

you goings need the leak flashlight to pinpoint the leak.

just sprayed results later

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..

Used this in a high caustic (potassium hydroxide, ph13) line cleaner. Tracer is stable and easy to see.
