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.
Total alkalinity controls how stable your hot tub’s pH stays. Get it wrong and nothing else in your water works right. This guide covers the correct target range, how to adjust it step by step, and the mistakes most new owners make.
Test strips are fast and good enough for daily checks, liquid reagent kits are more accurate for weekly balancing, and digital readers are the most precise but not required for most owners. The right answer depends on how closely you want to track your water and how much time you want to spend doing it.
Inflatable hot tubs aren’t low-maintenance, but they’re not complicated either. The key is knowing what’s different about them versus a hard-sided spa and building a realistic weekly routine around those differences. This guide covers exactly that.
Summer is the hardest season for hot tub water chemistry. UV light destroys sanitizer, heat accelerates chemical reactions, and more people in the tub means faster contamination. This guide covers exactly what to adjust and when.
Hot tub shock comes in two types: non-chlorine (MPS) and chlorine-based. Each does a different job. Knowing which one to reach for – and when – saves you cloudy water, skin irritation, and wasted product. This post breaks down both types clearly.
Low calcium hardness is one of the most overlooked hot tub chemistry problems. Soft water slowly corrodes equipment and surfaces by pulling minerals from whatever it touches. This guide explains what soft water does, how to test for it, and exactly how to fix it.
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.
Cloudy hot tub water has a short list of causes, and most of them are fixable in under an hour. This guide ranks them by how often they actually happen and walks you through each fix with specific numbers – no guesswork required.
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.
