📋 How it works▾
Lo-Chlor Miraclear Cube 50g is a slow-dissolving clarifier cube that drops into the skimmer basket and provides continuous water clarification for up to 30 days — no measuring, no dosing, no effort.
The cube works constantly as pool water passes through the skimmer, releasing clarifying agents that coagulate fine suspended particles and direct them to the filter. The result is consistently clearer, sparkling water with zero maintenance between cube replacements.
Lo-Chlor Miraclear Cube 50g details
Continuous 30-day clarification — one cube per month
Simply drop into the skimmer basket — no measuring or pouring
50g cube size — suits pools up to 60,000L
Safe for all filter types — sand, cartridge and DE

Compatible with all pool types and sanitiser systems
The Cube is ideal for ongoing clarity maintenance. For treating existing cloudiness, Lo-Chlor Miraclear Liquid Clarifier acts faster and is stronger for immediate results. For a smaller pool or as a starter cube, the Lo-Chlor Miraclear Cube 35g suits pools up to 40,000L. For severely murky water that needs settling to the floor before vacuuming, Lo-Chlor Maxi-Floc Plus is the stronger solution.

💊 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 50g cube into the skimmer basket. Replace when dissolved or at the 30-day mark, whichever comes first.
Large pool (60,000+ L)
2 cubes
per 30 days
For pools above 60,000L, use two cubes simultaneously in the skimmer for full coverage.
First-time use
1 cube + liquid top-up
For pools that haven't used a clarifier recently, add one cube and dose once with Miraclear Liquid for a faster start.
Ongoing routine
Replace monthly
Simply check and replace the cube monthly as part of your routine. Consistent use prevents fine particle buildup.
❓ FAQ▾
How is the Cube different from the Miraclear Liquid?▾
The Cube dissolves slowly over 30 days for continuous background clarification — ideal for maintenance once the pool is already clear. Miraclear Liquid Clarifier is faster-acting and 20% stronger — the right choice for treating existing cloudiness. Many pool owners use both: Liquid to clear a problem, then the Cube to maintain clarity ongoing.
What's the difference between the 35g and 50g cube?▾
The 35g cube is sized for pools up to 40,000L. The 50g suits pools up to 60,000L. Both provide up to 30 days of continuous clarification. If you have a larger pool (60,000L+), use two 50g cubes simultaneously. The Miraclear Cube 35g is also a good option for smaller pools where the 50g dissolves a little faster than ideal.
Do I need to remove the cube when shocking the pool?▾
No — the Miraclear Cube is compatible with chlorine shock treatments. Leave it in the skimmer during regular chemical dosing and shocking. It will not be affected by the elevated chlorine levels during a shock treatment.
My cube dissolved in less than 30 days. Is that normal?▾
Dissolution rate varies with water flow and temperature. Higher pump run times and warmer water can accelerate dissolution. If your cube consistently dissolves in less than 3 weeks, consider using a 50g cube in a pool using only a 35g, or check your pump run time is appropriate for the pool size.
