Mo-Clean – Natural Pond Clarifier
Introducing Mo-Clean, a natural solution that keeps water clear without using chemicals.
It suppresses the growth of unwanted algae without disturbing the ecosystem.
Unlike conventional algaecides, Mo-Clean does not harm aquatic plants or fish, but safely removes harmful algae with eco-friendly ingredients.
It balances water quality and improves the overall health of the pond ecosystem.
- Use 0.3 ml per 1 ton (1,000 liters) of pond water.
- Highly cost-effective.
- For best results, combine with beneficial filter bacteria.
●Features
Many types of algae exist in ponds and koi tanks, growing rapidly under sunlight, warm temperatures, and excess nutrients (phosphorus, nitrogen). During nutrient-rich seasons, algae can bloom explosively.
The main harmful types for koi ponds are:
- Green algae (e.g., Spirogyra): Form stringy growth, spoiling appearance
- Blue-green algae (cyanobacteria): Produce toxins, form scums, and release foul odors
Conventional algaecides suppress photosynthesis and kill algae, but they also harm beneficial plants and fail to address nutrient overload.
That’s why Mo-Clean is different.
Instead of chemicals, it provides nutrients for beneficial microorganisms (diatoms), which outcompete harmful algae by consuming available nitrogen and phosphorus.
Diatoms, with their silica-based “glass-like” cell walls, absorb sunlight more efficiently than green or blue-green algae, giving them a natural advantage.
This creates a healthier pond ecosystem where diatoms thrive, algae blooms are suppressed, and water remains clear—without disturbing the ecological balance.
- Effective even against existing algae blooms (blue-green scum)
- Reduces reliance on chemicals and UV sterilizers
- Cost-effective: very small amounts are sufficient
- Harmless to fish and plants, safe for long-term use
Natural pond care takes time, but the results are worth it.
