Science + Innovation at work.

We always go above and beyond to continuously improve, innovate, and bring the highest quality to every aspect of our products, services and relationships.























Invents Sani-King

Joe’s father, Lloyd King, invents the Sani-King spa feeder that revolutionizes hot tub care by introducing the first erosion-style, automatic bromine delivery system for hot tubs.

Sani-King Adjust-A-Flo

The next invention for hot tubs was an adjustable floating bromine dispenser called Adjust-A-Flo. SPA FROG® will replace this in a few years.


Joe and Lloyd together introduce the Perform-Max; a unique erosion design pool feeder that precisely meters chlorine or bromine for swimming pools.

Joe purchases King Technology

Joe purchases the pool and spa division of King Technology from his father and starts out on his own with a handful of employees in a home office and one production and shipping facility.

International selling

Joe begins selling internationally with the Perform-Max to great success in Europe, South America and Canada.

New Water®

The company introduces the New Water® line for swimming pools with pre-filled replaceable chlorine pacs that eliminate the annoyances of handling chlorine with even more precise feeding that makes chlorine last longer.


King Technology introduces the FROG® Mineral System for swimming pools—it becomes an overnight hit by reducing chlorine levels to a low 0.5 ppm* and making water feel softer and look crystal clear with much less work.


This unique mineral sanitizer is tailor-made for hot tubs; it quickly and easily fits inside a hot tub filter core.

Instant FROG®

King Technology was on a roll finding new niches for mineral products. The next one was for existing in-ground pools with a mineral product that simply sits in a skimmer basket called Instant FROG®.


The POOL FROG® XL Pro® was designed for in-ground pools to provide extended pac life to the chlorine by using a 6 lb chlorine pac in one cycler and a mineral reservoir in the other cycler. 



FROG BAM came onto the scene offering a unique 90-day algae preventive. Dispensed through the Pool FROG System, it’s so powerful we offer an algae protection guarantee!
