TetraAqua 100ml NitrateMinus

Easy to use algae control that reduces nitrates to below 40mg/litre.

• 100ml size treats 88 gallons
• 50ml sizes treats 220 gallons

Safe with all fish and plants in fresh and salt water aquariums

• biological nitrate reduction in easy to use liquid format    
• long-term improvement of the water quality    
• helps control the growth of algae    
• long-term reduction of the nitrate level to below 30 to 40 mg/l (depending on the aquarium conditions)     
• higher dosages (up to double strength) can be used to decrease nitrate levels even further    
• for both freshwater and marine aquaria

High nitrate levels can encourage excessive algal growth, which can make the aquarium look unsightly. Unlike other nitrate reducing products, which need regular recharging and replacing, NitrateMinus is simply added weekly to the aquarium. Also unlike many ordinary nitrate reducing products, Nitrate Minus does not need to be added to a filter system to work, but is simply added straight to the water.

How It Works

NitrateMinus utilises a natural biological process called denitrification to remove nitrate. Under conditions of low oxygen, such as are found under the gravel in most aquariums, special bacteria use nitrate instead of oxygen to break down the NitrateMinus granules.

By doing so, they steadily reduce existing nitrate levels, and maintain a permanently low level. In addition to removing nitrates, NitrateMinus also releases a low level of carbonates into the water, which helps to stabilise the pH of the water.

How to Use It

Simply add the required dose of NitrateMinus to the aquarium once a week to keep nitrate levels low. NitrateMinus must be in an oxygen poor environment to work. The effectiveness of NitrateMinus may therefore be reduced in aquariums with undergravel filters.
