Pool Equipment – Sanitiser FAQs #

  • What is the main difference between chlorine, saltwater, mineral and freshwater pool systems?

    • Chlorine pools use manually added chlorine or automated dosing.

    • Saltwater pools create chlorine from dissolved salt using a chlorinator.

    • Mineral pools use magnesium/potassium blends with low levels of chlorine.

    • Freshwater systems sanitise using UV, ozone and ionisation with minimal chemicals.

  • How does a chlorine pool work?

    Chlorine is added manually or via an automatic doser. It forms hypochlorous acid, which kills bacteria and keeps the pool safe.

  • What are the advantages and disadvantages of chlorine pools?

    Pros:

    • Lowest upfront cost

    • Highly effective sanitisation

    • Supplies widely available

    • Works in all climates

    Cons:

    • Can irritate eyes and skin

    • Noticeable chemical smell

    • Requires regular manual testing and dosing

    • Imbalances can cause corrosion or “shocking”

  • Who is a chlorine pool best suited for?

    Budget-conscious families who don’t mind weekly water balancing and chemical handling.

  • How does a saltwater pool work?

    A salt chlorinator converts dissolved pool salt into chlorine through electrolysis, providing steady sanitisation without manual chemical dosing.

  • What are the pros and cons of saltwater pools?

    Pros:

    • Softer, gentler water feel

    • Minimal chlorine smell

    • Automatically maintains chlorine levels

    • More stable water chemistry

    Cons:

    • Higher upfront setup cost

    • Salt can affect nearby metal and natural stone

    • Salt cells require cleaning and periodic replacement

  • Is a saltwater pool still a chlorine pool?

    Yes — salt chlorinators produce chlorine. The difference is the water feels softer and the system requires less hands-on chemical handling.

  • Who is a saltwater system best for?

    Families wanting easy maintenance, soft-feeling water, and fewer chemicals to handle manually.

  • What is a mineral pool and how does it work?

    Mineral pools use blends of magnesium and potassium salts combined with low levels of chlorine. The system still sanitises via chlorine but delivers a softer, “luxury” water feel.

  • What are the pros and cons of mineral pools?

    Pros:

    • Very gentle on skin and hair

    • Therapeutic, spa-like water

    • Reduced chemical use

    • Premium water clarity

    Cons:

    • Higher upfront cost than standard salt

    • Minerals can be more expensive to top up

    • Still reliant on small amounts of chlorine

  • Who should choose a mineral pool?

    Homeowners wanting premium water comfort, especially those with sensitive skin or who enjoy a high-end swim experience.

  • How does a freshwater system work?

    Freshwater systems use a combination of UV, ozone and ionisation to sanitise water. They use minimal chemicals and only trace chlorine when required.

  • What are the pros and cons of freshwater pools?

    Pros:

    • No chlorine smell

    • Extremely gentle on skin, hair and eyes

    • Very low chemical usage

    • Eco-friendly

    Cons:

    • Highest upfront cost

    • Requires attentive monitoring

    • Less common than other systems

    • May require a small backup sanitiser in some conditions

  • Who is a freshwater pool best suited to?

    Eco-conscious families, swimmers with sensitivities, or anyone wanting the most natural swimming experience possible.

  • Which pool sanitisation system is the cheapest to install?

    Traditional chlorine systems have the lowest upfront cost.

  • Which system is the easiest to maintain?

    Saltwater and mineral pools offer the most stable chemical levels and lowest weekly maintenance.

  • Which system provides the most comfortable water?

    • Freshwater: highest comfort

    • Mineral: very high

    • Saltwater: high

    • Chlorine: moderate comfort

  • Which system is best for sensitive skin or allergies?

    Freshwater is the gentlest, followed by mineral systems.

  • Are chemical smells reduced with alternative systems?

    Yes. Saltwater and mineral systems have minimal smell, while freshwater has no chlorine smell at all.

  • Which system is the most eco-friendly?

    Freshwater systems use the least chemicals and offer the strongest eco credentials.

  • Do mineral or freshwater systems still need chlorine?

    • Mineral pools: Yes, but far less than traditional systems.

    • Freshwater systems: Often use trace levels or a small backup, depending on the system.

  • Which sanitiser has the lowest long-term running cost?

    Saltwater and mineral systems generally have the most predictable and stable long-term costs. Chlorine is cheap upfront but can cost more over time due to chemical use.

  • How do I choose the best system for my family?

    • Chlorine: Cost-effective and simple

    • Saltwater: Best balance of cost, comfort and maintenance

    • Mineral: Wellness-focused, premium comfort

    • Freshwater: Ultimate softness and eco performance, but higher upfront cost
