Healthy koi start with stable, clean water. Our Pond Water Treatment range helps you manage common pond issues like green water, algae growth, cloudy water, and poor water balance. These treatments are designed to support clearer water, reduce organic waste buildup, and help maintain a healthier environment for koi and other pond fish—especially during warm weather, high feeding periods, or after heavy rain.
Whether you’re treating an active algae problem or maintaining water quality week to week, the right product can make pond care simpler and more consistent.

How to choose the right pond treatment

Before you dose, confirm:
  • Pond volume (litres) so you can dose accurately
  • The problem you’re treating: green water (suspended algae) vs string algae vs cloudy water
  • Filtration and UV status: some treatments work best alongside mechanical filtration and UV
  • Fish safety: follow label directions and avoid overdosing
Tip: For ongoing clarity, combine good filtration, regular maintenance, and consistent dosing based on your pond size. If you’re unsure what to use, contact Pool Mecca with your pond volume and symptoms and we’ll recommend the best option.
