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

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

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.

The liquid was not green at all, and was closer to a red black and totally useless.

Worked exactly as expected. Was able to find the water seeping into my yard was from the septic system. Did take a little longer to show them thought, but when it did it was very noticeable.

Just what I ordered

This worked as we thought a a little bit goes a long way be sure to wear gloves when pouring.

It works!

Works great and highly concentrated. Also a very good value compared to the supply houses.

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.
