Concentrated Red Tracer Dye - Highly Concentrated Fluorescent Water Tracing & Leak Detection Dye - One Gallon (128 Ounces)

this product works fine

Bought this for a halloween prop .It lights up a neon read in UV light . Don't overdo it you don't need much

For it's stated purpose it probably works. It was bright. I tried using it to dye my farm pond red for my son's birthday/Halloween as nobody makes a red pond dye but it didn't work well for that purpose at all. Not the sellers fault, they made no statements saying it would.

If I had only known a little can go a long way! Lol. In our case it wasn’t showing up a soon as we thought it should. So after a few minutes we dumped the rest of the jug down the drains. Then it appeared in our basement drive and just kept on and on. Looked like a red river. We hosed it down trying to dilute it and to get it to flow on away because we were worried our pets would drink it. Anyway, all is well and after a few days it’s disappeared and didn’t seem to stain the cement.

Bottle cap is red advertisement label says red comes out Pink we are using it. The 5 star rateing is for Pink color not for red

Used this product to locate where water was coming and going on our property and worked as intentioned.

I was able to verify my sump pump was just recycling the same water. no Stains left behind

you can really see it in a pond
