📋 How it works▾

Lo-Chlor Ultra-Kleer 4-in-1 Clarifier is the most comprehensive single clarifier product in the Lo-Chlor range — combining clarification, algae inhibition, phosphate removal and scale prevention in one weekly dose.

For pool owners who want to simplify their chemical routine without compromising on water quality, the 4-in-1 handles four common pool maintenance needs simultaneously — reducing the number of individual products required and making weekly treatment more efficient.

Lo-Chlor Ultra-Kleer 4-in-1 details

  • 4-in-1 formula: clarifier + algae inhibitor + phosphate removal + scale prevention
  • Simplifies weekly maintenance into a single product
  • Safe for all filter types — sand, cartridge and DE
  • pH neutral — does not affect water balance
  • Available in three sizes: 1L, 5L and 20L
  • Particularly beneficial for pools on hard water or bore water with phosphate issues

Choosing your size: The 1L is ideal for trying the product or for smaller pools. The 5L is the best-value option for regular weekly maintenance on a standard residential pool. The 20L drum suits commercial pools or service professionals.

For the 2-function version covering only clarification and algae inhibition, Lo-Chlor Ultra-Kleer 2-in-1 is more economical if phosphate and scale aren't concerns. For dedicated high-strength phosphate removal, Lo-Chlor Starver X is the specialist product. For severe cloudiness, Lo-Chlor Maxi-Floc Plus settles debris to the floor faster than any clarifier.

🔍 Does it suit my pool?▾

Select your pool type or surface for specific guidance.

🧂Salt chlorinated▾
✓ Compatible — particularly beneficial for salt pools
Salt pool owners benefit from the scale prevention component, which helps protect chlorinator cell plates from calcium buildup. The phosphate removal function also helps in salt pools where swimwear and sunscreen introduce phosphates regularly.
💧Traditional chlorine▾
✓ Compatible — works with all chlorine systems
Safe for all chlorine pool systems. Apply with the pump running and circulate for at least 2 hours.
🪨Mineral / magnesium▾
✓ Compatible — safe for mineral systems
Safe for mineral and magnesium pool systems. Does not interact with mineral sanitiser chemistry.
⚡Ionised / Nature2▾
✓ Compatible — safe for ionised systems
Fully compatible with ionised and Nature2 pool systems.
🏊Fibreglass▾
✓ Compatible — safe for fibreglass
Safe for fibreglass 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. Do not add to the skimmer box. Run filter for at least 8 hours after application.

Weekly maintenance
100 ml
per 50,000 L
Standard weekly dose. Add after backwashing for best results. Consistent weekly use delivers the full 4-in-1 benefit.
Cloudy water treatment
250 ml
per 50,000 L
Higher dose for visible cloudiness. Results typically within 4–8 hours with continuous filter running.
Large pool (5L or 20L)
Scale dose
proportionally
Dose per 50,000L and scale for pool volume. Broadcast evenly. The 20L drum suits pools needing bulk weekly supply.
High phosphate water
Use alongside Starver X
For pools with very high phosphate levels (above 600 ppb), the phosphate component in Ultra-Kleer maintains low levels but isn't sufficient for initial knockdown. Use Starver X first.
❓ FAQ▾
Does the 4-in-1 replace all my other chemicals?▾
It replaces the need for separate clarifier, algae inhibitor, phosphate remover and scale preventer in your weekly routine. It does not replace your primary sanitiser (chlorine or salt), your dedicated algaecide like Lo-Chlor Pool Algaecide, or shock treatments. Think of it as simplifying your weekly top-up routine, not replacing your full chemical program.
How is this different from the Ultra-Kleer 2-in-1?▾
The Ultra-Kleer 2-in-1 covers clarification and algae inhibition. The 4-in-1 adds phosphate removal and scale prevention. If you're on hard water, bore water, or you have recurring phosphate issues, the 4-in-1 is worth the additional cost. If your water source is relatively clean and soft, the 2-in-1 covers the essentials more economically.
Will the phosphate removal in this replace Starver X?▾
For maintenance of low phosphate levels, yes — the 4-in-1 keeps phosphates from building up between treatments. For initial knockdown of high phosphate concentrations (above 600 ppb), you still need Lo-Chlor Starver X. Use Starver X first if levels are elevated, then maintain with the 4-in-1 weekly.
Which size is right for me?▾
For most residential pool owners, the 5L provides around 10 months of weekly maintenance on a 50,000L pool — good value for ongoing use. Try the 1L first if you want to test the product before committing to a larger size. The 20L drum is for pools requiring bulk supply.
