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

Worked as promised. Instructions for various uses on label or sent with with product would be helpful.

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

Septic tank

you goings need the leak flashlight to pinpoint the leak.

Could have been a little stronger concentrate.

Good product

That is what I needed.

Works as it should. Used it to diagnose septic leach field problems. Instructions were clear. I dumpee the appropriate amount for my septic tank size and a day later inspected. Worked great.

OK product

just sprayed results later
