Product Description

TNC Carbon provides a safe, easy to use alternative to a CO2 gas injection system. It is an ideal solution if installing gas cylinders is either impractical, too complicated, or too expensive.
In the natural environment, Carbon is an essential requirement for plants.

Plants source the Carbon from CO2 absorbed through the leaves. Most plants contain chlorophyll – the pigment which makes plants green. The chlorophyll absorbs light and the plant uses the energy from the light to convert the Carbon together with water (H2O) into sugars and carbohydrates (CH2O) – a process known as photosynthesis.
The sugars and carbohydrates provide the energy for the plant to grow.

TNC Carbon is ideal for use with TNC Complete and with TNC Plugs. It can also be used with other propriety aquarium fertilisers or as a supplement to an EI dosing regime.

Add 1ml per 50 litres of tank water per day.
Stronger doses must be used with caution

Contains :- 2% Gluteraldahyde

    Have used this liquid carbon, along with TNC lite, since planting up a new 360l (no CO2) aquarium which is well stocked with fish. The plants are thriving and the fish happy. Very good value from this company and prompt delivery.

    Use this in my mums 240ltr tank instead of co2 gas and the plants thrive when it’s used in conjunction with the fertiliser tabs also from TNC.
    Would highly recommend it as a cost effective alternative for anyone not ready to go with a full gas set up.
    Delivery is next day and you receive regular updates regarding your orders progress.

    Works very well with TNC lite, dose rate makes it good value for money. This will be my third order for 1l size.
