Green Water Tracing & Leak Detection Flourescent Dye - 1 Gallon

Works great, especially when it makes contact with water.

We tried this in our man-made pond to find a leak. We didnt find the leak, its just too small we think. But we sure have green water. The pond has been green for about 4 days now. The fish and salamanders dont seem to be affected. Note: a little goes a long way.

Good product. Easy to use.

Used this to see where a field tile was routed to....wow did it work!

Works Great

Does the job

Used it to find a leak in my hot tub. Works well with a fluorescent black light, less well with the LED UV light. Good product.

Little expensive but it’s worth it. I didn’t use it for finding a leak. It served its purpose. Don’t get scared of the orange color when you get it because it will be green when you add it in water!

Have only run a few sample tests, but it definitely turns the water green and can be seen pretty well with a UV light. I only used a few drops in a gallon of water, and that worked pretty well. Want to run a few more tests before trying to figure out leakages in a water feature and fish pond. So far, so good.

Lights up very well under UV light. Used for a Halloween decoration and it worked great.
