Setting up a new hot tub correctly from the first fill prevents months of water problems. This guide walks through every chemical step in the right order, with specific targets and common mistakes to avoid before you ever step in.
The first week with a new hot tub sets the tone for everything that follows. This practical day-by-day guide covers what to test, what to adjust, and how to build habits that keep your water clean without making it a part-time job.
A hot tub party can wreck your water chemistry in one evening if you go in unprepared. The fix is a simple before-during-after routine: pre-treat your water, set chemical levels higher than normal, and shock immediately after everyone clears out. Here’s exactly how to do it.
A strong chlorine smell in your hot tub is almost never caused by too much chlorine. It’s usually chloramines, which form when sanitizer reacts with contaminants brought in by bathers. The fix is shocking the water, not adding less chlorine.
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.
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.
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.
