Tetra NitrateMinus 250ml

Tetra NitrateMinus 250ml

Tetra NitrateMinus 250ml is a nitrate-reducing water conditioner for freshwater and marine aquariums. It is made for aquarists who want to lower nitrate (NO3-), a key algae nutrient, in a natural way and keep water values steadier. It suits anyone dealing with algae-prone water in a community, planted or marine tank.

Key Benefits

• Reliably reduces nitrate (NO3-), a key nutrient for algae, using natural methods
• Helps prevent algae, since excess nutrients are a common cause of algal blooms
• Helps stabilise water values
• Supports better water quality and a healthier aquatic environment
• Works biologically, which minimises the need for chemical treatments
• An eco-friendly way to maintain balanced water
• Works in both freshwater and marine aquariums

How It Works

The particles added to the water act as a substrate that stimulates microorganism activity. These microorganisms feed on nitrate and break it down biologically, which improves water quality. Because it relies on natural biological processes rather than harsh chemical intervention, it fits well into a routine aimed at keeping the tank ecosystem balanced.

How to Use

• Shake well before use.
• Add the dose to the aquarium water once a week.
• The visible particles will spread out and then sink slowly. This is normal for the product.
