📋 How it works▾
Lo-Chlor Miraclear Cube 35g is a slow-dissolving clarifier cube sized for smaller pools — dropping into the skimmer basket to provide continuous water clarification for up to 30 days with zero measuring or maintenance.
As pool water passes through the skimmer, the cube releases clarifying agents that coagulate fine suspended particles and direct them to the filter. The 35g size is calibrated for pools up to 40,000L, dissolving at a rate that provides consistent clarification without over-treating smaller pools.

💊 Dosage guide▾
Drop the cube directly into the skimmer basket. Replace when fully dissolved — approximately every 30 days.
Standard use
1 cube
per 30 days
Drop one 35g cube into the skimmer basket. Suited to pools up to 40,000L. Replace when dissolved.
Larger pool (40–60,000L)
Use 50g cube instead
For pools above 40,000L, the Miraclear Cube 50g provides better coverage per cube. Alternatively, use two 35g cubes simultaneously.
First-time use
1 cube + liquid top-up
For pools without recent clarifier use, add one cube and dose once with Miraclear Liquid for a faster initial result.
Ongoing routine
Replace monthly
Simply replace monthly as part of your routine. No measuring needed — consistent use prevents fine particle accumulation.
❓ FAQ▾
How is the 35g different from the 50g cube?▾
The 35g is sized for pools up to 40,000L. The Miraclear Cube 50g suits pools up to 60,000L. Both provide up to 30 days of continuous clarification. The 35g dissolves at a slightly slower rate in smaller pools, providing more consistent coverage without over-treating the water.
How is the Cube different from Miraclear Liquid?▾
Miraclear Liquid Clarifier is faster-acting and 20% stronger — the right choice for treating existing cloudiness quickly. The Cube is for ongoing maintenance — it provides continuous background clarification that keeps a clear pool sparkling with no effort. Use Liquid to fix a problem, then the Cube to maintain clarity.
Do I need to remove the cube when shocking?▾
No — the Miraclear Cube is compatible with chlorine shock treatments. Leave it in the skimmer during regular chemical dosing. It will not be affected by the elevated chlorine levels during a shock.
My pool is clear — do I still need a cube?▾
A clear pool can become hazy quickly in warm weather or with heavy use. The Cube provides preventative protection — keeping particles coagulated and directed to the filter before they cloud the water. Think of it like a regular pool service: easier to maintain clarity than to recover it.
