Cold temperatures affect how hot tub chemicals dissolve, how fast sanitizer burns off, and how often you need to test. This guide covers the specific chemistry adjustments that matter when the temperature drops below freezing outside your tub.
If your hot tub pH climbs back up within a day or two no matter how much pH decreaser you add, you are not doing anything wrong – the tub itself is fighting you. This post explains the real reasons pH keeps rising in hot tubs and gives you a step-by-step fix that actually sticks.
Bromine and chlorine are both effective hot tub sanitizers, but they have real differences in cost, smell, ease of use, and performance at high temps. This breakdown covers what actually matters so you can pick the one that fits your setup and stop second-guessing yourself.
Bad-smelling hot tub water is almost always a chemistry problem, not a cleanliness problem. The smell tells you exactly what’s wrong. This guide walks you through the most common odors, what causes each one, and how to fix it without draining the tub unnecessarily.
If you add chlorine or bromine and the reading drops to zero within hours, something is actively consuming your sanitizer. This post walks through the six most common causes and how to fix each one without guessing.
Total alkalinity is the foundation of stable hot tub water. Get it wrong and your pH will bounce around no matter what you add. This guide explains the right target range, how to adjust alkalinity up or down, and the order of operations that saves you from fixing one problem and creating another.
Test strips are the most popular way to test hot tub water, but they’re also the least accurate. Liquid kits are more reliable for pH and alkalinity, and digital readers are worth the investment if you soak frequently. Here’s how to pick the right tool for how you actually use your hot tub.
Inflatable hot tubs are easier to own than hardshell spas in some ways, but they come with their own maintenance quirks. Thinner walls, no built-in ozone, and portable filtration mean you need to stay on top of chemistry more often, not less. This guide gives you a realistic, specific routine that works.
Summer is the hardest season to keep a hot tub balanced. UV rays burn through sanitizer, heat accelerates chemical reactions, and more bather traffic means more organic waste. This guide explains what’s actually happening and gives you a practical summer routine to keep your water safe and clear.
Hot tub shock isn’t one product — it’s two different tools that solve different problems. Non-chlorine shock (MPS) oxidizes waste and clears cloudiness fast, while chlorine shock kills bacteria and resets contaminated water. Knowing which to reach for, and when, is what separates a tub that stays clear from one that constantly fights you.
