Green Water Tracing & Leak Detection Flourescent Dye - 1 Gallon

I am not a plumber and I didnt know what options existed to help me find out where my sump pump discharged to, but this product did exactly what I needed it to. I was a bit confused when the product arrived and was a dark red liquid in the bottle, but as soon as it touches water it turned green. I did buy a UV flashlight at the same time as buying this because I assumed it was needed, but for my use case the green color was enough for me to see in a storm drain outside my house without using the flashlight. This was a great low cost solution and saved me from having to rent plumbing hardware or higher a professional. Awesome solution!

A little goes a long way. Used this to find a leak in our koi pond, about 2500 gal. Used less than a quarter of the gallon. Looked like someone melted neon crayons in th pond. Easily found the leak. Plenty left over to use in our smaller pond for Halloween--for many years!

I use it in a prop fountain for my Halloween display. Color stays bright and a little goes a long way!

it definitely works well in my water. I was afraid that I wouldn’t really be able to see it but it’s like a neon and you definitely don’t have any trouble seeing it when you put it in the water works well.

Works well but definitely have to use more than I thought to get the desired effect for a puking skeleton Halloween prop.

The media could not be loaded. This worked perfect for our homemade puking skeleton Halloween decoration. You only need a little bit of the tracer dye and it lights up perfectly with black lights. It was easy to use and lasted great through the season. We still have a lot left over for Halloween this year.

I used this product for an outdoor Halloween decoration, the vomiting Skelton and it worked fantastic. My spouse did use this to detect a leaking toilet flapper. It has multiple uses and works well.

This stuff glows like crazy under UV light. Very little is needed to be added to the water. I used this as part of my drinking pirate display for Hallowwen last fall.
