Pool Leak Detection Dye Kit - with 2 Precision Applicators - Made in USA - Superior Long Lasting UV Pool Dye Easily Locates Leaks - for All Pool, Spa, & Hot Tub Types - 8 OZ Fluorescent Yellow

Easy to use,works very well,Very easy to see in the water.this is a great kit to have if you think your loosing water.

I was a little skeptical at first about how visible the UV dye would be in the water, especially with the sun and shade in my pool, but it works amazingly well. The color shows up clearly—even in darker areas—which made it super easy to check for leaks. Fortunately, I didn’t find any active leaks this time, but I’m really glad I have this on hand for the future. There’s a generous amount of product included, so it’ll last through multiple uses. Definitely recommend for peace of mind!

Bottle of dye opened and foil peeled back. Dye all over my hands and kitchen counter. I needed it right away so I used the dye kit. It worked well. I was pleased with the product.

The media could not be loaded. My video shows my first try using this fluorescent dye.My pool has a very slow leak from the spa into the pool. I'm convinced that the leak is through a grout line either below or between the single row of tiles that surround the top of the spa. The spa water drips through the stone wall separating it from the pool all night after the pump shuts off.The instructions on the dye bottle call for positioning the dispensing tip 1/2" from the suspected leak.Not knowing where the leak was, I held the tip maybe 6" above the water surface and dispensed a ribbon. The dye did not seem to disappear through a leak but I did see dye entering the pool below. I wasn't able to tell exactly where the leak was. This was obviously not the best way to dispense the dye.I'll try again by dispensing small quantities of dye near each vertical grout line, one at a time, until I can track down the leak.I have no doubt that I'll be able to locate my leak but it's small enough that it will take time.I like the ease with which I can see the dye in my pool and how it disperses slowly in calm water. As the description says, it does look fluorescent in daylight - like a yellow-green.The kit came with plenty of dye and two syringes with two different dispensing tips. I've been needing a syringe like this for years for precision dispensing of glue, but I couldn't find one.The bottom line: This is a nice leak detection kit at a good price.

Works great! Easy to see if there is/are leaks

Works well

I never found the leak using this a stuff but it works great. Dispersed over several minutes, very visible in the water, and I'm confident my water leak isn't within the pool but likely in a pipe. Highly recommend

Great for finding a leak in your pool.. I found mine and was able to fix it.
