Swim and Soak Bromine and chlorine are both effective hot tub sanitizers, but bromine handles heat better and is gentler on skin, while chlorine is cheaper and easier to shock with. The right choice depends on how you use your tub and how much maintenance you want to do.
Keeping a hot tub clean takes real time, but probably less than you think if you stay on top of it. This breaks down the actual weekly, monthly, and quarterly tasks with realistic time estimates so you know what you’re signing up for.
Bad hot tub smell is almost always a chemistry problem, a biofilm problem, or both – and the fix depends on which one you’re dealing with. This guide walks through every common hot tub odor, what’s causing it, and exactly how to fix it fast.
A hot tub that won’t hold a chlorine or bromine reading usually has one of five root causes: high bather load, unbalanced pH, a biofilm problem, combined chlorine buildup, or UV degradation. This post walks through each cause and tells you exactly what to do about it.
Total alkalinity is the most overlooked number in hot tub chemistry, but it controls almost everything else. Get it wrong and your pH will swing constantly, your sanitizer won’t work properly, and you’ll be chasing problems for weeks. Here’s how to dial it in correctly from the start.
Not all hot tub water testing methods are equal. Test strips are fast but rough, liquid kits are more accurate, and digital readers are precise but pricey. Here’s how to pick the right one for how you actually manage your hot tub.
Hot tub store shelves are overwhelming, but most owners only need five or six core chemicals to keep their water clean and safe. This guide breaks down exactly what each one does, what order to add them, and which products are worth skipping entirely.
Inflatable hot tubs are more work than hard-shell spas, but a simple weekly routine keeps them clean and safe all season. This guide covers the specific chemical targets, filter habits, and water change schedule that actually work for inflatable models. No fluff, just the routine.
Summer is the hardest season for hot tub chemistry. UV light destroys chlorine, heat speeds up chemical reactions, and more bathers mean more contaminants. This guide covers exactly how to keep up.
Not all hot tub shock is the same, and grabbing the wrong one can make your water worse. This guide breaks down exactly when to use non-chlorine shock versus chlorine shock, how much to add, and what each one actually does to your water.
