Green Water Tracing & Leak Detection Flourescent Dye - 1 Gallon

great dye solution. easy to see and works well. 5 stars

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.

This is a great product and is very easy to use.

Needed to find where gutter was draining and about a cup in the drain followed by running the hose in the drain for 5 minutes created a fluroescent green river by the output on the street. It worked exactly as advertised and yes the liquid is orange in the bottle.

I didnt use it for what its intended for but I know it will work great for it!! I used mine for Halloween to make my skeletons look like their drinking an puking posion!poison!! And I pour 1 cup liquid to 4 gallons of water and it turned neon green! You can see the neon in the day with out UV light or with UV and it looks amazing!! My Halloween props looks amazing with it!! And im sure I have enough to last me for 2-3 years!!! Love it so much!!!!

Found my septic tank leak immediately mixing a little of this into my tank and using a black light at night.

Worked well. Dye takes several days to fade away. Our sump pump goes to our pond, so pond was neon green for a few days or a corner of it. Only takes a little bit to use, not entire gallon.

Worked great- saved me thousands in excavation fees.

I was luckily able to prove a city engineer wrong about old storm sewer connections that did not have any plans in the city files and save a lot of problems.

This stuff is brilliant--in more ways than one! Its super concentrated and super visible, and allowed me to sort out the bizarre drainage system on the property I recently purchased. Im totally satisfied.
