Green Tracing Dye - Highly Visible Concentrated Fluorescent Leak Detection Dye - 1 Gallon

Very easy to use and effective. Very good value.

A little goes a long way, and this stuff does show with UV light as advertised.

This product was easy to use.

Easy, found & marked hot tub leak

I used this product to track down a leak in my lawn sprinkler system and it only took about 10 minutes to track down the problem and replace the broken pipe. I would recommend this product. It did the job and didnt kill any plants or grass.

Very visible on the ground when I am doing septic inspections.

Used to trace were drainage was leaking from. Did a good job. Easy to follow. Last for days . Maybe have used to much but worked well.

So easy to use … no mess and brute color

this looked cool in my fountain under black lights

Used to find where water was flowing into sump pit from lake. This worked beautifully and was easy to see.
