Where to Start

Pick the problem in front of you right now.

01

Water Gone Wrong

Cloudy, milky, foamy, green or smelly? Start with the water problem guides — the checks in the order that clears most tubs, and when draining beats another dose.

02

Choose Your Chemistry

Chlorine or bromine? Which shock? Strips or a liquid kit? Our chemistry decisions weigh the choices for how you actually use your tub.

03

Winter and Running Costs

Keep it running through a UK winter or drain and store? Work out what your tub really costs to run on your own tariff.

04

Drain, Refill and Filters

How often to change the water, how to drain an inflatable without a pump, and when a filter needs replacing rather than rinsing — start here.

What We Cover

41 guides on the hot tub problems UK owners actually search for.

💧 Cloudy, Foamy & Green Water

What causes each symptom, what to check first, and when the honest answer is to drain and start again.

🧪 Chlorine, Bromine & Shock

Which sanitiser suits how often you use the tub, how much an inflatable really needs, and what shock is for.

⚖️ pH & Alkalinity

Why balance comes before sanitiser, what UK hard water does to it, and how to stop the numbers drifting.

❄️ Winter, Costs & Filters

Heat loss, running costs on your own tariff, freezing risk, draining and storing, and filter care.

Why Tub and Pool Answers?

Search any hot tub water problem and nearly every answer comes from someone selling the fix — a dealer, a chemical brand, or the tub's maker. Some of that advice is right. A lot of it ends with another bottle.

We're not a dealer or a chemical brand. Every guide is researched from product labels, makers' manuals, UK water-treatment guidance and what owners report in real discussion threads — and it tells you what to test, what to change first, and when the fix is simply less.
