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 (Vibrant Blue)

Work very well.

Came on time and just perfect in every way!!!

This thing worked like magic, after adding fix-a-leak with no success i purchased this to see if i could find this leak to try to fix it. I shut the machine off and started squirting at each jet /inlet/ outlet. When there is no leak the dye doesn’t get dragged in the jet. In my case i had a drip drip every sec . When i came to the area of the leak this dye gets dragged into the chamber like very obvious. I couldn’t be happier with my purchase. Thank you for this product.

Great item and very good customer service and brilliant communication

The blue dye was very visible even in the darkness of the pool light niche. The long straight needle and long bent needle were very good for emitting the dye into confined parts of the pool. The amount of dye supplied was more than sufficient as just a full needle of dye lasted for checking many areas.
