Built in Houston, by people tired of $60 chlorine.
Same active ingredients as the big chains. Often the same manufacturers. Without the retail markup, the loyalty-card games, or the upsells.
Houston pool owners have been overpaying for decades.
One chain has dominated pool chemicals in Houston for as long as most of us have owned pools. You know the one. Their pricing reflects that grip — a $20 bucket of trichlor tabs there is wholesaling for half of that, and they're betting you don't have the time to shop around.
We started Longhorn because we got tired of the math. Tired of "loyalty members" paying $5 more than walk-ins. Tired of pH increaser marked up 4×. Tired of being told a "specialty algaecide" was the only thing that would work — when it was just polyquat 60 in a different jug.
So we built the store we wanted to shop at: honest pricing, same chemistry, no upsells.
Three things we do — and don't.
Honest pricing
What you see is what you pay. No "member-only" tiers, no club fees, no fake retail price designed to make a 5% discount look like a deal.
Bulk discounts kick in automatically when you buy 4+ of anything. That's it.
Same chemistry, fair markup
Trichlor is trichlor. Cal-hypo is cal-hypo. We never claim we sell the same exact products as the big chains — but the active ingredients are identical, often from the same wholesalers.
We list the active ingredient and concentration on every label.
Local people, local warehouse
Family-owned and operated in Houston. The person who answers the phone is the person who'll meet you at curbside. No call centers, no offshore support, no script.
Text us a test strip photo. We'll read it for you.
Five things we'll always do.
We won't sell you stuff you don't need.
If your CYA is already at 50 ppm, you don't need a stabilizer top-up. We'll tell you.
We'll show our work.
Every product page lists the active ingredient, concentration, and dosing math. No mystery formulations.
If we don't carry it, we'll tell you where to get it.
Need a part for a 2003 Hayward pump? We don't sell pumps — but we know who does in Houston. We'll point you.
Water testing is free, forever.
Bring a sample. We'll test it in 10 minutes and tell you exactly what to add — even if you don't buy anything from us.
If we mess up, we'll fix it.
Free returns within 30 days, no restocking fee, no "approved reason" required. We'd rather lose a sale than lose a neighbor.
Three ways to put us to work.
