Innovation in Leisure Water Treatment
Auto-Dosing: The Future of Hot Tub & Pool Sanitisation
ChloroKlean is pioneering automatic dosing systems for the leisure market, delivering consistent, hands-free chlorine dioxide sanitisation to hot tubs and pools across holiday parks, lodges, and commercial leisure facilities.
The Problem with Manual Dosing
Holiday lodge parks and leisure operators face a constant challenge: keeping dozens or even hundreds of hot tubs and pools safely sanitised while managing staff turnover, guest behaviour, and compliance obligations. Traditional chlorine and bromine treatments rely on manual testing and dosing, a process that is labour-intensive, inconsistent, and leaves gaps in protection between checks.
Inconsistent sanitiser levels between manual tests, creating windows where bacteria can multiply
Heavy reliance on staff to test and dose correctly. Training gaps and human error are inevitable
Bromine and chlorine degrade rapidly in warm water, requiring frequent intervention to maintain safe levels
The Auto-Dosing Solution
ChloroKlean's auto-dosing systems continuously monitor water conditions and deliver precise, measured doses of chlorine dioxide (the primary sanitiser) directly into the water circuit. This removes the reliance on manual intervention and ensures consistent, round-the-clock protection.
Continuous, automated dosing maintains a constant sanitiser residual with no gaps in protection
Chlorine dioxide as the primary sanitiser replaces chlorine and bromine entirely
Reduces staff workload dramatically. No more twice-daily manual testing and dosing rounds
Why Auto-Dosing with ChloroKlean Changes Everything
When chlorine dioxide is delivered via auto-dosing, it becomes the sole primary sanitiser. No bromine, no chlorine tablets, no secondary chemicals required.
Eliminates Bacteria Continuously
Auto-dosing maintains a consistent ClO₂ residual that controls Legionella, Pseudomonas, E. coli, and biofilm 24/7, not just at the point of manual dosing.
No More Bromine or Chlorine
ChloroKlean replaces both bromine and chlorine as the primary sanitiser. No chloramines, no bromamines, no chemical smell, no bleached swimwear.
Reduced Health & Safety Risk
Automated systems remove the risk of under-dosing or over-dosing. No hazardous tablet handling, no chemical storage rooms full of bromine tubs.
Better Guest Experience
Crystal clear water without the chemical smell or skin irritation guests associate with chlorine and bromine-treated hot tubs.
Biofilm Prevention Built In
Continuous low-level ClO₂ dosing prevents biofilm from establishing in pipework, the root cause of persistent bacteria issues in leisure hot tubs.
Less Staff Time, More Consistency
Auto-dosing replaces manual testing rounds with automated monitoring, freeing maintenance teams for other tasks while improving compliance.
Built for the Holiday Lodge Park Market
Holiday lodge parks face unique water treatment challenges that auto-dosing with ChloroKlean is specifically designed to solve. With guests arriving and departing on tight changeover schedules, dozens of hot tubs needing simultaneous attention, and regulatory requirements demanding robust Legionella management, the case for automated chlorine dioxide dosing is compelling.
Multi-Unit Management
Manage sanitisation across 50, 100, or 200+ lodge hot tubs from a centralised system. Auto-dosing scales effortlessly. Adding units doesn't mean adding staff.
Guest Changeover Ready
Automated systems maintain safe water quality between guest stays. No risk of a hot tub being missed on a busy changeover day.
Compliance Confidence
Continuous dosing and monitoring provides an auditable trail of water treatment, valuable evidence for HSE inspections and due diligence.
Operational Savings
Reduced chemical costs (no bromine), fewer staff hours on manual dosing, less reactive maintenance from bacteria or biofilm issues, and fewer guest complaints.
"Auto-dosing with chlorine dioxide is the single biggest step change the holiday park hot tub market has seen. It removes the inconsistency of manual dosing, eliminates the need for bromine entirely, and gives park operators genuine confidence that every hot tub on their site is continuously protected. The reduction in bacteria-related incidents, guest complaints, and staff workload makes it an operational no-brainer."

"We developed the Spa System kits because hot tub owners deserve a simpler, safer alternative to chlorine tablets and bromine. The Core Kit gets you started with water treatment, while the Pro Care Kit gives you the complete maintenance cycle, covering pipework, surfaces, filters, and water. Chlorine dioxide is already the trusted choice in commercial pools, hospitals, and water treatment, and these kits bring that same technology to your hot tub at home."

The Pro Care Kit is the complete whole-spa maintenance cycle, covering water, system, filters and surfaces.

The Core Kit covers water sanitisation and clarity, everything you need for ongoing water treatment. The Pro Care Kit includes everything in the Core Kit plus three additional maintenance products: Spa Purify for internal pipework cleaning, Spa Clean for surface deposits, and Spa Filter Renew for cartridge filters. Choose the Core Kit to get started, or the Pro Care Kit for complete whole-spa maintenance.
Yes. The ChloroKlean Spa System works with all types of hot tubs including inflatable, acrylic, fibreglass, and rotomoulded models. The low-dose liquid formula is gentle on all surfaces while providing effective sanitisation.
ChloroKlean uses chlorine dioxide (ClO₂), not traditional chlorine. Unlike chlorine tablets or granules, chlorine dioxide does not form chloramines, the compounds responsible for strong chemical smells, eye irritation, and bleached swimwear. It also penetrates biofilm in pipework, which tablets and granules cannot do.
Both kits contain 2 x 500ml bottles of Spa Protect, which typically provides several weeks of treatment for a standard domestic hot tub depending on usage, bather load, and water temperature. Test strips are included so you can monitor levels and dose accordingly.
The Core Kit is designed to be a complete water treatment solution. Spa Protect handles sanitisation and biofilm control, Spa Clarify keeps water crystal clear, and the test strips let you monitor water balance. You may still need pH adjusters depending on your source water. For complete spa maintenance including pipework, surfaces, and filters, consider the Pro Care Kit.
Yes. Because chlorine dioxide does not form chloramines or bromamines, it is significantly gentler on skin and eyes compared to traditional chlorine or bromine treatments. Many users with sensitive skin or conditions like eczema report improved comfort when switching to ChloroKlean.
