Review on 🔴 Highly Concentrated Red Tracer Dye - 1 Gallon (128 fl oz) by Dennis Reed

Works great for tracing drainage lines in my yard. I have a 150 year old farmhouse on 2 acres and I really have no idea where the drainage goes. I used this material to trace my 80 year old septic system and easily found the result. Definitely works well, and a little goes a long way. I poured about a liter of this down my septic tank and after a few weeks it was still pink. This material is great when you need to trace lines. I haven't had a chance to test it in my garden so I can't say how good it will look on/in the ground. I've only used it on pipes, both PVC and clay.
