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

Didn’t help find the leak in our pool at all. Turned it a purple color . Had to drain whole pool.

Easy to use. Helpful product

Used it to find a leak in the hot tub. Got me into the exact place just like I hoped.

This helped me identify what and where water was draining.

I tried this after using the green dye before. My UV light barely picked this stuff up in a bucket. Im going back to the green.

Found the leak in my boat.

That is what I needed.

Works as it should. Used it to diagnose septic leach field problems. Instructions were clear. I dumpee the appropriate amount for my septic tank size and a day later inspected. Worked great.

Worked good for what I needed it for.

Worked great for tracing drainage lines in my yard. I have a 150+ yr old farmhouse on 2 acres and I really have no idea where drainage goes. I used this stuff to trace my 80+yr old septic system and easily found the output. Definitely works well and a little goes a long way. I dumped about a quart of this in my septic and it was still coming through pink after a few weeks. This stuff is great if you need to trace lines. I wasn’t able to test it in an area of my yard so i can’t say how well it would show up on/in the ground. I only used it for pipes, both pvc and clay.
