Soft water in a hot tub sounds harmless, but low calcium hardness is one of the most damaging imbalances you can ignore. It causes foamy water, etched shells, and corroded equipment. This post explains what’s actually happening and gives you a specific fix.
Cloudy hot tub water usually comes down to one of four things: off pH, low sanitizer, a clogged filter, or water that’s just overdue for a drain. This guide walks you through how to tell which one you’re dealing with and what to do about it.
Getting hot tub chemistry right on the first fill sets you up for months of easy maintenance. This guide walks through every step in the correct order, with specific targets for each parameter, so you don’t end up chasing water problems from week one.
The first week with a new hot tub sets the tone for everything that follows. Get the chemistry balanced before you ever soak, and you’ll spend a lot less time chasing problems later. This guide walks you through exactly what to do, day by day.
A hot tub party is one of the fastest ways to destroy your water chemistry. Six people in 400 gallons introduces a flood of contaminants that your sanitizer can’t handle alone. This guide walks you through exactly what to do before, during, and after a big soak to keep the water safe and clear.
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.
If your hot tub pH keeps drifting upward no matter how much pH decreaser you add, you’re not alone. The cause is almost always high total alkalinity, aeration from jets and air blowers, or both. This post explains why it happens and what to actually do about it.
Bromine and chlorine are both effective hot tub sanitizers, but they’re not interchangeable. Bromine holds up better in hot water and is gentler on skin, while chlorine works faster and costs less. Which one is right depends on how you use your tub and how much maintenance you want to do.
A bad smell in your hot tub almost always points to one specific problem, and the type of smell tells you exactly where to look. This guide matches each odor to its cause and gives you a direct fix. Most problems resolve in under an hour.
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.
