📋 What it tests▾
The AquaFresh/AquaSpa 4-in-1 Test Kit by LaMotte is the dedicated water testing kit for pools and spas using the AquaFresh non-chlorine (PHMB) or AquaSpa non-chlorine systems — the only accurate way to monitor the four key parameters of these systems.
Standard DPD chlorine test kits cannot measure PHMB sanitiser levels, hydrogen peroxide, or the specific parameters needed for non-chlorine pool chemistry. This kit tests all four: PHMB/biguanide level, hydrogen peroxide, pH and total alkalinity — giving complete water quality information for AquaFresh and AquaSpa pool and spa owners.
AquaFresh/AquaSpa 4-in-1 Test Kit details
Tests four key parameters: PHMB biguanide level, hydrogen peroxide, pH, and total alkalinity
LaMotte reagent quality — professional accuracy for home use
Suitable for AquaFresh pool and AquaSpa spa non-chlorine systems
Essential for monitoring and maintaining the non-chlorine system correctly
Cannot be substituted with standard DPD chlorine test kits
This test kit is essential equipment for any AquaFresh or AquaSpa system. Without accurate PHMB level readings, you cannot confidently manage the system. Use alongside AquaFresh Sanitiser, AquaFresh Enhance and AquaFresh Performance for a complete non-chlorine pool management approach.
🔍 Is it right for my system?▾
This test kit is designed specifically for non-chlorine PHMB pool and spa systems.
✅AquaFresh pool system▾
✓ Essential for this system
This is the correct test kit for AquaFresh pool systems. Test weekly to maintain optimal chemical levels.
🛁AquaSpa spa system▾
✓ Also suitable for AquaSpa
The same kit works for AquaSpa non-chlorine spa systems. Test more frequently due to smaller water volume.
💧Standard chlorine pool▾
✗ Not designed for chlorine pools
Standard chlorine pools don't use PHMB or hydrogen peroxide. A standard DPD test kit is the correct choice for chlorine pool testing.
🔬Professional / pool service▾
✓ Suitable for professional testing
Professional pool technicians servicing AquaFresh or AquaSpa pools should use this kit for accurate readings.
🧪 Testing guide▾
Regular testing keeps the AquaFresh system balanced and effective.
Test PHMB level
Weekly
target 30–50 ppm
Test sanitiser level weekly. Dose AquaFresh Sanitiser to top up if below 30 ppm.
Test pH
Weekly
target 7.2–7.6
PHMB systems still require correct pH. Add pH increaser or reducer as needed.
Test total alkalinity
Monthly
target 80–120 ppm
Alkalinity buffers pH against rapid changes. Adjust with sodium bicarbonate if below 80 ppm.
Test hydrogen peroxide
As needed
0 ppm target
Hydrogen peroxide should be zero in an AquaFresh system. Presence indicates residual from other products.
❓ FAQ▾
Why can't I use a standard chlorine test kit?▾
Standard DPD test kits react with chlorine to produce a colour reading. PHMB doesn't react with DPD reagents — a standard kit would show zero chlorine (correct) but cannot measure PHMB at all. You'd have no way of knowing whether your sanitiser level is adequate.
How often should I test?▾
Test PHMB and pH weekly. Test alkalinity monthly. Test more frequently when first starting the system or after significant water additions, heavy rain, or high bather loads.
What should I do if PHMB reads low?▾
Add AquaFresh Sanitiser to bring levels back to the 30–50 ppm target range. Low PHMB means inadequate disinfection — the pool is not properly sanitised. Don't swim until levels are restored.
