Two products. On purpose.
Most pools only need a sanitizer and a shock. So that is all we make, in the sizes you actually use. No aisle to wander, nothing in your cart you did not ask for.

“We didn't come to pool care from the backyard. We came to it from the inside.”
For 25 years our family has been in the chemical business here in Houston. We know how these products are made, where the good material comes from, and what it costs before anyone puts a label on it. And for 25 years we watched the same thing happen: solid, high-grade chemistry gets repackaged, marked up, and sold to homeowners through a store clerk and a “free” water test that somehow always ends in a full cart. We knew we could do better, because we already knew what was in the bag.
A Houston family
Made in America, run by a Texas family.
Made in the USA
Every poolvitamins product is manufactured in the United States. Real domestic chemistry, never offshored.
A family-owned small business
We're an independent Houston family, not a national chain or a big-box aisle. You buy from the people who actually answer the phone.
Support Texas Jobs
Every order keeps a Texas small business running and Texans working. Your money stays in the community, not at a corporate headquarters.
