Lo-Chlor is Australia's most trusted specialist pool and spa chemical manufacturer globally recognised and exporting to 25+ countries. Their range covers algaecides, clarifiers, phosphate removers, stain treatments, stabilisers, spa care, equipment aids and more, every product formulated for Australian water chemistry and climate.
Lo-Chlor Aquaguard CSM is a triple-action pool protection formula providing Cell protection, Scale prevention and Metal sequestration in a single weekly treatment — the most comprehensive equipment and surface protection product in the Lo-Chlor range.
The three-in-one formula works simultaneously: the Cell Protector component reduces scale buildup on salt chlorinator cells, the Scale Inhibitor prevents calcium deposits on surfaces and fittings, and the Metal Sequestrant keeps dissolved metals in suspension to prevent staining. Three separate maintenance concerns addressed with one weekly dose.
Cell — reduces calcium scale on salt chlorinator cell plates
Scale — prevents calcium scale on surfaces, fittings and pipes
Metal — sequesters dissolved metals to prevent staining
Weekly dosing for ongoing protection
Available in three sizes: 1L, 5L and 20L
Particularly valuable for salt pool owners
Choosing your size: The 1L is a good starting point for residential pools. The 5L is more economical for ongoing weekly use (about a year's supply for a 50,000L pool). The 20L suits commercial pools or service professionals.
Aquaguard CSM is the comprehensive approach. If you only need targeted metal sequestration, Lo-Chlor Metal Solution is more economical. If you only need scale prevention, Lo-Chlor Stain & Scale Defence is the dedicated product. Aquaguard CSM is ideal when all three are needed — which is the case for most salt pool owners.
🔍 Does it suit my pool?▾
Select your pool type or surface for specific guidance.
🧂Salt chlorinated▾
✓ Primary benefit — essential for salt pools
Salt pool owners benefit most from Aquaguard CSM. The Cell protection component specifically combats the calcium scale that builds on salt cell plates — the most costly maintenance issue for salt pool owners. Weekly dosing significantly extends cell life.
💧Traditional chlorine▾
✓ Compatible — works with all chlorine systems
Safe for all chlorine pool systems. Apply with the pump running.
🪨Mineral / magnesium▾
✓ Compatible — safe for mineral systems
Safe for mineral and magnesium pool systems.
⚡Ionised / Nature2▾
✓ Compatible — metal sequestration especially valuable
Ionised pools benefit from the metal sequestration component. Keeping copper ions from the ioniser in suspension prevents blue-green staining on surfaces.
🏊Fibreglass▾
✓ Compatible — safe for fibreglass
Safe for fibreglass and composite pool surfaces at recommended doses.
🧱Concrete / pebblecrete▾
✓ Compatible — safe for all hard surfaces
Safe for concrete, pebblecrete and tiled surfaces at recommended doses.
💊 Dosage guide▾
Add directly to pool water with the pump running. Weekly dosing maintains all three protective functions simultaneously.
Weekly maintenance
100 ml
per 50,000 L
Standard weekly dose. Add after backwashing for best results.
Hard water areas
150 ml
per 50,000 L
Increase dose slightly if calcium hardness is above 300 ppm. More frequent scale challenge requires more frequent protection.
Post-stain treatment
200 ml
per 50,000 L
After treating metal stains, use a higher dose to keep residual dissolved metals in suspension.
Large pool (5L or 20L)
Scale dose
to pool volume
The 5L provides approximately 50 weeks of weekly treatment for a 50,000L pool — about a year's supply.
❓ FAQ▾
Do I still need to clean my salt cell if I use Aquaguard CSM?▾
Yes — Aquaguard CSM significantly reduces scale accumulation but doesn't eliminate it entirely. Cell cleaning every 3–6 months (less frequently with Aquaguard than without) is still recommended. Use Salt Cell Cleaner Plus when cleaning is needed.
How is this different from Stain & Scale Defence?▾
Stain & Scale Defence covers scale prevention and metal sequestration. Aquaguard CSM adds the third element — dedicated Cell protection chemistry specifically for salt chlorinator cells. For salt pool owners, the Cell component makes CSM the more complete product.
Which size should I buy?▾
For most residential salt pools, the 5L provides about a year's worth of weekly treatments at 100ml per 50,000L. The 1L is a good way to trial the product. The 20L is for commercial or multi-pool properties.
