We are changing the pool care game.
Traditional pool chemical brands sell products with technical sounding names and instructions that are about as easy to interpret as hieroglyphics. You go to your pool store, wait in line to have your water tested, and the next thing you know you’re out a sizeable piece of your paycheck having been sold a whole assortment of products you’re not even sure you need.
Does it have to be that hard? The pool care industry doesn’t want you to know this, but the resounding answer is NO.
We are building a brand that makes it so much easier for the average pool owner to care for their own pool. With easy to understand instructions, top notch customer service and a suite of innovative products, Pool Day is making a splash. Thanks for letting us help you help your pool!
