Green Water Tracing & Leak Detection Flourescent Dye - 1 Gallon

I have been using this to complete dye tests on septic systems. Its orange until it comes in contact with water then it is flourescent green. A little goes a long way.

Great formleak detection

Excellent Product...

This is the tracing dye to use for leak detection. We have been very pleased with the brilliant green color of this product, especially when activated with either a 365nm or 395nm UV light source. We are currently conducting a dye tracer study of water infiltration and exfiltration of a storm drain system. This product adds stunning color to our underground pipeline video imaging.

Using to identify downspout outflow, well connections/leaking, and so forth. Working great. Looks orange in bottle but BRIGHT fluorescent green in water.

Bought to use on water line leak. I poured the whole gallon at the beginning of water line after purging all water. Turned on water left it pressurized for 2 days no green. Turned the outside water outlet on ,seen green in water turned it back off. Went back after 45 min when it got dark to seen if I could see with blacklight Nothing. It should have showed up. I saw green water come out, waste of money.

Did what it was supposed to do. Located the leak quite easily. Good product.

Great product

Does the job

I purchased the dye to help find a leak in the pond and used according to directions pouring it into my pond after I shut off the waterfall as directed. With the water still, the dye did not move much and did not go towards the leak as it should have. Instead, the entire water was green as the dye and hopelessly useless. Now I got almost a gallon of dye and out $29.
