> 3 dayHave only run a few sample tests, but it definitely turns the water green and can be seen pretty well with a UV light. I only used a few drops in a gallon of water, and that worked pretty well. Want to run a few more tests before trying to figure out leakages in a water feature and fish pond. So far, so good.

Greater than one weekI used this product to locate a leak in a sewer line, I only had to use very little and it worked great.

> 3 dayWe purchased this to confirm if our neighbors sewer was indeed leaking into our basement. They flushed it down their toilet and the green dye all over our basement was proof positive. Possibly saved a legal battle and a friend.

> 3 dayWe tried this in our man-made pond to find a leak. We didnt find the leak, its just too small we think. But we sure have green water. The pond has been green for about 4 days now. The fish and salamanders dont seem to be affected. Note: a little goes a long way.

Greater than one weekNot sure if I was unlucky with my batch, but my UV light and black light both failed to properly light up the liquid diluted in water (at a ratio that was more concentrated than suggested). While the yellow colour was very bright and fluorescent in colour when in the tub, the inability to light up under UV light meant that it was all but invisible on concrete (colour would not show after momentarily flowing over a concrete slab I tested on). Product works fine if you just want the colour, but would NOT RECOMMEND if you want the fluorescent properties. The cap was also cracked on arrival (but thankfully there was an inner seal. It just means I can not fully tighten and close the cap now and must keep it upright.
