📋 How it works▾

Lo-Chlor Miraclear Metal-Free Algaecide is the world's first metal-free pool algaecide — a landmark formulation from Lo-Chlor that kills and controls blue-green and black algae without copper, making it the correct choice wherever copper-based products create risk.

Traditional algaecides rely on copper compounds, which can cause staining in ionised pools, pools with old copper plumbing, or any pool where additional copper introduction is a concern. Miraclear Metal-Free solves this completely — delivering equivalent algaecide performance with a unique non-metallic, non-foaming, non-staining formula that also includes a built-in water clarifier.

Lo-Chlor Miraclear Metal-Free Algaecide details

  • World's first metal-free pool algaecide formulation
  • Kills and controls blue-green and black algae
  • Non-metallic, non-foaming and non-staining
  • Built-in water clarifier — improves water clarity alongside algae treatment
  • Ideal for ionised pools, Nature2, Zodiac mineral systems and copper-sensitive setups
  • Available in four sizes: 500ml, 1L, 5L and 20L
  • Compatible with all pool surfaces and sanitiser types

Choosing your size: The 500ml and 1L are ideal for residential pool owners maintaining a standard pool. The 5L suits larger pools or regular treatment schedules. The 20L is for commercial pools or service professionals.

Miraclear Metal-Free is the recommended algaecide for winter pool close in ionised systems — use instead of Lo-Chlor Winteriser Algaecide which contains copper. For post-treatment clarity, the built-in clarifier reduces the need for a separate Miraclear Liquid Clarifier dose.

❓ FAQ▾
Why is metal-free algaecide important?▾
Copper-based algaecides are the industry standard and work well in most pools. But in ionised systems, old copper-plumbed pools, or pools prone to staining, adding more copper risks visible discolouration — particularly at low pH. Miraclear Metal-Free delivers the same algaecide result without that risk.
What does 'built-in clarifier' mean?▾
The formulation includes clarifying agents that coagulate fine particles alongside the algaecide treatment. You'll often see improved water clarity as well as algae control from a single dose — reducing or eliminating the need for a separate clarifier product.
Can I use this in my ionised pool for winter close?▾
Yes — this is the recommended product for ionised pool winter closure. Use Miraclear Metal-Free instead of the copper-based Lo-Chlor Winteriser to avoid copper buildup during the colder months when the pool is less actively managed.
How is this different from Pool Algaecide?▾
Lo-Chlor Pool Algaecide uses a proven copper complex formula — the No. 1 preventative algaecide in AU & NZ. Miraclear Metal-Free delivers equivalent performance without copper, specifically designed for situations where copper is unsuitable. For most standard pools, Pool Algaecide is more economical. For ionised, Nature2 or copper-sensitive pools, Miraclear Metal-Free is the correct choice.
