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

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

I tried this after using the green dye before. My UV light barely picked this stuff up in a bucket. Im going back to the green.

Everything was good

Could have been a little stronger concentrate.

DID THE JOB

That is what I needed.

Didn’t help find the leak in our pool at all. Turned it a purple color . Had to drain whole pool.

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

you goings need the leak flashlight to pinpoint the leak.
