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

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

Dye does not show up at double concentration or higher. Does not show with UV light even even at full concentration.

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..

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.

Everything was good

This helped me identify what and where water was draining.

Worked good for what I needed it for.

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

Worked very well to find 2 water leaks.

Could have been a little stronger concentrate.
