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.

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.
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.
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.
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.
Hot tub jets can fail in a handful of specific ways, and most of them point to different root causes. This guide walks through weak jets, pulsing jets, jets that won’t spin, and jets with no flow at all – so you can figure out what’s actually wrong before spending money on a service call.
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.
