Description

A product for controlling phosphate levels in ponds

AF Phosphate Minus Pond is an effective preparation designed to reduce phosphate levels in garden ponds and ornamental water features.

An imbalance between phosphates and nitrates promotes the growth of cyanobacteria and nuisance red algae. Thanks to its unique formula, the product binds dissolved phosphates without affecting vitamin levels or essential trace elements required by pond inhabitants.

Regular use helps maintain crystal-clear water and creates ideal conditions for aquatic plant growth. It is especially recommended for ponds with a high fish load and limited plant mass, where the risk of excess phosphates is particularly high.

The product is also highly effective before and after winter, when phosphate levels are typically elevated — helping restore biological balance and prevent algae blooms.

What makes this product unique?

  • Effectively binds and reduces phosphates, one of the main causes of excessive algae growth in ponds
  • Limits algae and cyanobacteria development, helping maintain stable water conditions
  • Reduces water turbidity and supports natural clarity, improving overall water quality
  • Helps maintain biological balance, especially in heavily stocked ponds
  • Safe for plants and aquatic organisms — reduces excess phosphates without affecting vitamins and trace elements

Dosage

Place the product in a filter basket using 1 kg per 10,000 liters of water.

I’m using PO4 Minus. After changing the media, I see a drop in KH, magnesium, and calcium. Is the media causing this? Why?

Author: krzysztof.mandecki@aquaforest.pl

Yes, Phosphate Minus KH drop is a known side effect. Phosphate Minus is a filtration medium that selectively binds phosphates from the water. However, its use may slightly influence KH (carbonate hardness) due to its chemical activity. Drops in magnesium and calcium are typically unrelated, but they may appear due to other factors like biological […]

I’m using Stone Fix and noticed high silicate levels in my water. Testing shows that Stone Fix may be releasing silicates. Should I be concerned, and how can I fix it?

Author: krzysztof.mandecki@aquaforest.pl

Stone Fix and silicates – this issue can occur, especially in newly established tanks. Most mineral-based materials (rocks, adhesives, sands, zeolites) may release small amounts of silicates into the water. This is a natural and usually temporary process. To reduce silicate levels, perform regular water changes and use Phosphate Minus, which effectively removes both phosphates […]
