Total alkalinity is the chemical buffer that keeps your hot tub pH from swinging all over the place. Getting it into the 80-120 ppm range is usually the first step to stable, comfortable water. This guide walks through testing, raising, lowering, and maintaining alkalinity without chasing numbers in circles.
Test strips are fast and good enough for weekly checks. Liquid kits are more accurate for troubleshooting. Digital readers are the most precise but cost more upfront. This post breaks down when each method makes sense and which mistakes to avoid with all three.
Hot tub chemical kits can look overwhelming, but you really only need a handful of core products. This guide breaks down what’s essential, what’s situational, and what you can skip entirely – with specific numbers so you know exactly what you’re aiming for.
Inflatable hot tubs are more demanding than most owners expect – smaller water volume, softer walls, and no built-in insulation all create unique challenges. This guide gives you a specific, weekly routine that works for the real conditions of an inflatable spa.
Hot tub owners often grab whichever shock is on the shelf without knowing there’s a real difference. Non-chlorine shock oxidizes contaminants and lets you soak sooner. Chlorine shock kills bacteria and is the right call when your water is genuinely compromised. Knowing which to use – and when – saves you a lot of frustration.
Running a hot tub typically costs between $20 and $100 per month, depending on your climate, tub size, cover quality, and how often you use it. Electricity is the biggest expense, but chemicals and filter replacements add up too. This breakdown covers all three so you know what to actually expect.
Low calcium hardness is one of the most overlooked hot tub chemistry problems. Soft water aggressively corrodes surfaces and equipment, and fixing it is simpler than most owners expect. This guide covers the target range, the risks of ignoring it, and exactly how to bring calcium hardness up.
That slimy gunk coming out of your hot tub jets is biofilm – a bacterial colony living inside your plumbing. It survives regular sanitizer doses and won’t go away on its own. This guide explains what biofilm is, how to flush it out completely, and how to keep it from building back up.
Most hot tubs need a full drain and refill every 3 to 4 months, but heavy use, foam, or stubborn cloudiness can push that timeline earlier. This post explains exactly how to tell when your water is done, how to stretch it a little longer, and what to do on refill day to start fresh.
Hot tub jets can fail in several ways – weak pressure, no spin, air lock, or complete shutdown. Most problems come down to a few root causes: clogged filters, air locks, closed diverter valves, or a struggling pump. This guide walks you through diagnosing each one so you know what you’re dealing with before calling a tech.
