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

The media could not be loaded. Worked as advertised. Was able to verify a suspected leak very quickly.

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.

It works very well but be careful as it will stain concrete

Great product for any pool owner. No way to miss a leak with the fluorescent yellow. As it says, very easy to locate a leak. Good value for the price. It comes with two applicators. A little bit of product goes a long way. Not work buying food coloring to detect a leak.

Works as advertised. Color stands out in water. Only wish I had a needle 2 ft long to be able to get to lights.

This was incredibly easy to use and saved me almost 200 in call out cost for a leak detection company. Turned the pump off, waited 15 mins for water to settle amd went to the usual suspects, skimmer mouth, corners of steps, jets. 2nd jet had a leak that was made extremely obvious at the dye was.getting sucked into a hole the size of a grain of sand! Used pool putty to repair and so far so good. There is plenty in the bottle (doesn't even look like I used any to be honest) so it will last a lifetime. Great value at this price if you're handy and don't mind getting wet!.

Useless unless the leak is sizable.

Recommend for the price
