### What You're Currently Spending on Pool Chemicals
A typical UK chlorine pool costs £600 to £2,000 per year in pool chemicals alone: chlorine tablets, liquid chlorine, pool shock treatment, pH adjusters, algaecide. Add the swimming pool maintenance visits, typically 6 to 12 per year, and the total annual pool chemical treatment bill is significant.
Mineral+Biome® removes every one of those costs. The pool water is maintained by a biological system that manages itself. Monthly pool maintenance visits become twice-yearly technical service calls. No chemistry call-outs in between. No pool water testing kits. No weekly dosing. No pool cleaning service calls for chemistry problems.
Looking for a natural alternative to pool chlorine? The natural alternative to chlorine in pool water is biology, not another chemical: Mineral+Biome® is not a chlorine substitute for water treatment that swaps one product for another. It removes the need for disinfectant chemicals altogether.
## How the Retrofit Works
Your existing pool stays exactly as it is. The upgrade happens in the plant room. Your current chlorine system, whether that's tablet feeders, a salt chlorinator, or a dosing pump, is removed. The Mineral+Biome® system is installed into your existing filtration circuit and connected to your flow and return manifolds.
A new energy-efficient pump is fitted at the same time, along with touch-screen controls that automate backwash cycles, dosing and performance monitoring. The pool is drained, the installation takes 1–2 days, and the pool is refilled and ready to swim in. No builder. No groundworks. No disruption beyond 1–2 days.
### What Changes After the Upgrade
- No pool chemicals to buy or store
- No weekly pool water testing
- No pool shock treatments
- No pool maintenance calls for chemistry problems
- Softer water, no chlorine smell, no red eyes, no skin irritation
- 2 technical service visits per year instead of 6 to 12
## Refurbishing Your Pool? Fit the System While It's Drained
A pool refurbishment is the cheapest moment to change how your water is treated. Whether the pool renovation is a new liner, retiling, resurfacing or a plant room upgrade, the pool is drained and the plant room is open anyway. Mineral+Biome® goes into the existing filtration circuit in 1–2 days, with no plumbing changes, alongside the rest of the swimming pool refurbishment.
Tell your pool renovation company before the work is scheduled, or send us their brief and we will specify the water treatment for them.
## Is Your Pool Suitable?
Most existing pools are. Mineral+Biome® works with concrete pools, fibreglass shells, vinyl liner pools, indoor pools, outdoor pools, heated pools and swim spas. The requirement is a working pump and accessible plant room, if you have a pool with an existing filtration circuit, the retrofit is possible.
Indoor pool owners see the biggest immediate change. Chlorine in an enclosed pool building produces trichloramines, the gas responsible for the sharp smell and respiratory irritation in traditional indoor pools. The swimming pool maintenance costs for indoor pools are also highest. Mineral+Biome® eliminates trichloramines entirely from day one.
"We switched from a saltwater pool last year. The difference is immediate, no chemical smell, no red eyes, and we have not touched a chemical since."

### Frequently Asked
Is there a genuine alternative to chlorine in pool systems, or just salt?
Salt systems and UV still rely on chlorine or ozone dosing. A genuine alternative to chlorine in pool systems is Mineral+Biome®, it replaces chemical disinfection entirely with a self-sustaining mineral ecosystem, and retrofits to any existing pool in 1–2 days.
Can you convert pool to chemical free without draining and rebuilding?
Yes, we convert pool to chemical free in 1–2 days, no rebuild, no replumbing. The existing chemical system is removed and Mineral+Biome® is installed into your current filtration circuit.
Looking for a chlorine free pool near me, does retrofit work UK-wide?
Yes. Retrofit installation is available across the UK for anyone searching for a chlorine free pool near me, most existing pools qualify, and we confirm suitability as part of your free specification.
Can my existing pool be upgraded?
Most can. Concrete, fibreglass, vinyl liner, indoor, outdoor, heated pools and swim spas are all suitable. The requirement is a working pump and accessible plant room. We confirm suitability as part of the free specification.
How long does the installation take?
One to two days. The pool is drained, the existing chemical system is removed, Mineral+Biome® is installed into your filtration circuit, and the pool is refilled. No structural work. The pool is ready to swim in the same day.
What happens to my existing pool equipment?
The plant room is stripped and replaced with the Mineral+Biome® system, a new energy-efficient pump, and touch-screen controls. Your pool shell, pipework, heating and cover stay in place.
How much will I save on pool maintenance?
Pool chemical costs drop to zero. Monthly maintenance visits reduce to just two per year. No chemistry call-outs between them. Electricity costs fall because the biological system requires lower pump speeds than conventional filtration. Most installations see payback within 3–7 years, depending on pool type and size.
Can I still heat my pool?
Yes. Mineral+Biome® operates comfortably up to 30 degrees Celsius, with a maximum operating temperature of 32 degrees. All existing heating systems are retained.
Is pool chlorine bad for your skin?
Yes. Chlorine strips the skin's natural oils and breaks down the protective moisture barrier. Regular exposure causes dryness, itching and irritation in most swimmers. People with eczema, psoriasis or contact dermatitis commonly find chlorinated water triggers flare-ups. Mineral+Biome® uses no chlorine. The water is mineral-based and biologically balanced, most pool owners describe it as feeling closer to spa water.
Can pool chlorine cause eczema or dermatitis?
Chlorine is a documented irritant for skin conditions including eczema and contact dermatitis. It disrupts the skin barrier, removes moisture and introduces reactive compounds that trigger inflammation. If anyone in your household has a skin condition, a chemical-free retrofit removes the exposure entirely, no chlorine, no chloramines, no chemical additives of any kind.
What happens to the pool smell and red eyes after the retrofit?
Both disappear. The chemical smell comes from chloramines, compounds formed when chlorine reacts with sweat and organic matter. Red eyes are caused by chloramine exposure, not water itself. Mineral+Biome® produces no chloramines. Pool owners consistently report no chemical smell, no eye irritation, and noticeably cleaner-feeling water from the first swim.
Should I change the water treatment during a pool refurbishment?
If you are going to change it at all, yes. A refurbishment drains the pool and opens the plant room, so fitting Mineral+Biome® then adds 1–2 days to the programme instead of a separate drain-down later.
When is the best time of year to refurbish a pool?
Most UK owners plan a pool refurbishment for the off-season so the pool is back in use for summer. Searches for pool refurbishment peak between January and April, so get the specification done before you fix dates.
Can you remodel an existing pool?
Yes. Most pools can be relined, retiled, resurfaced or given a new plant room without rebuilding the shell. The water treatment can change at the same time: Mineral+Biome® retrofits into the existing filtration circuit.
