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

Shipped fast, great price, and it worked but it would have been nice to have instructions noting about how many ounces to add per gallon.

this looked cool in my fountain under black lights

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

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

Very easy to use and effective. Very good value.

great for verification of under ground utilities

Just what I needed .

Used this product for tracing sewers in a network-product performs great. Ordered 1 gallon through Amazon previously, this time I ordered 2 and unfortunately 1 of the caps slightly loosened and began leaking. Each of the gallons were in sealed plastic bags but the one bag was not sealed 100% tight. Caught this before it turned into a disaster as this is basically the stuff they dye the Chicago River with on St Patricks day so potential for huge mess. Suggest redundant bags for preventing leaks and bubble wrap when multiple containers sent in same box.

This product was easy to use.

Still havent found the drains. It does stain heavily so be careful not to spill or get it on your hands. Takes a long time to wear off! May work better for othera needs not so much for ours. We wanted to know wherw are down spouts and floor drains led and.atill no.clue.
