Explain like Iʼm 5 version: Max Shock is like a super-cleaner for your pool. It kills the bad stuff, like bacteria and algae, and makes your water safe and clear to swim in.
Full explanation: Max Shock is a fast-dissolving, highly concentrated pool sanitizer. It works by releasing a high dose of chlorine into the water, which oxidizes contaminants and bacteria. This process sanitizes the pool, leaving your water clean and safe for swimming.
Hereʼs the deal: most pool shocks are pretty similar when you look at the ingredients. What sets Max Shock apart is our focus on top-quality ingredients, Max Shock PDP3super clear instructions, and next-level customer service. Plus, we offer peace of mind that what you're getting is safe, properly packaged, and EPA approved. No shady suppliers here!
Use one pound of Max Shock for every 10,000 gallons of water. Youʼll start to get a feel for what your pool needs based on usage, weather, and water clarity.
Shocking once a week is a good rule of thumb. But if your pool gets a lot of action, or youʼre dealing with algae or cloudy water, you might need to shock more frequently

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!
