That sharp chlorine odor coming off your hot tub usually means your water has a chloramine problem, not a chlorine surplus. Chloramines form when chlorine bonds with contaminants and stops working as a sanitizer. Shocking the water breaks them apart and kills the smell.
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.
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.
Most hot tubs need fresh water every 3 to 4 months, but heavy use, foam, or chemicals that won’t hold can push that timeline shorter. This guide gives you a simple formula to know exactly when your water is done.
Foamy hot tub water is almost always caused by something that shouldn’t be in the water: body lotion, detergent residue, or a chemistry imbalance. This guide walks you through the real causes and how to clear foam fast, without draining unless you have to.
A strong chlorine smell from your hot tub usually isn’t caused by too much chlorine – it’s caused by chloramines, which form when chlorine bonds with sweat, oils, and other contaminants. Shocking the water breaks chloramines apart and gets rid of the smell. This post explains what’s happening and exactly how to fix it.
That slime in your hot tub lines is biofilm — a bacterial colony that hides in your plumbing and resists normal sanitizer levels. This guide walks you through exactly how to purge it, what products to use, and how to keep it from coming back.
Most hot tub owners are told to change their water every 3 months, but the real answer depends on how often you use it and what’s in the water. This post covers the signs your water is done, a simple formula to calculate your actual drain schedule, and how to squeeze more life out of each fill.
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.
