Adding sanitizer to your hot tub but the reading drops to zero within hours? This is one of the most common – and most frustrating – hot tub problems. The cause is almost always one of a handful of things: high demand from organic contamination, biofilm in your plumbing, pH out of range, or a stabilizer problem. Here’s how to figure out which one you’re dealing with.
Most hot tub owners buy way more chemicals than they need, or miss the two or three that actually matter. This guide breaks down the essential chemicals, what each one does, and which extras are worth keeping on the shelf.
Getting your hot tub chemistry right at startup sets the foundation for every soak after it. This guide walks you through the exact sequence, the right target numbers, and the mistakes most first-timers make before they ever get in.
A party puts serious stress on hot tub water. Body oils, lotions, sweat, and drinks can crash your sanitizer and throw your pH sideways within an hour. This guide walks you through exactly what to test and fix, in what order, so your tub is clean and safe again fast.
Keeping a hot tub clean doesn’t require hours of work each week. A simple, consistent routine — test twice a week, add chemicals as needed, rinse your filter monthly — handles 90% of problems before they start. This guide breaks it down into the smallest possible effort that still actually works.
A bad smell from your hot tub almost always points to a specific chemical or biological problem – and the smell itself tells you which one. This guide walks through the most common hot tub odors, what each one means, and exactly how to fix it. No guessing required.
If your hot tub tests at zero sanitizer an hour after you add chemicals, something is consuming it faster than it can work. The usual culprits are high bather load, out-of-range pH, low cyanuric acid, or biofilm hiding in your plumbing lines. This post walks through each one so you can find your actual problem.
Hot tub chemical kits can look overwhelming, but you really only need a handful of core products. This guide breaks down what’s essential, what’s situational, and what you can skip entirely – with specific numbers so you know exactly what you’re aiming for.
Bromine and chlorine are both effective hot tub sanitizers, but bromine handles heat better and is gentler on skin, while chlorine is cheaper and easier to shock with. The right choice depends on how you use your tub and how much maintenance you want to do.
A hot tub that won’t hold a chlorine or bromine reading usually has one of five root causes: high bather load, unbalanced pH, a biofilm problem, combined chlorine buildup, or UV degradation. This post walks through each cause and tells you exactly what to do about it.
