Muy buena calidad

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.

Thought I'd need maybe half the bottle to check all around my liner for leaks, but turns out half a syringe was more than enough, making this apparently enough for years to come. Easy to use. Was able to identify two small leaks.

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.
