Tropical Carbo Liquid Carbon Fertiliser for Aquatic Plants

Tropical Carbo is a liquid carbon fertiliser designed for planted aquatic setups. Carbon is essential to photosynthesis — without a reliable supply, aquatic plants struggle to grow, water parameters become harder to manage, and algae gains the upper hand. This product delivers carbon in liquid form, making it accessible to plants immediately and consistently.

How It Works

Carbon is one of the primary building blocks of photosynthesis, directly driving the production of organic compounds that fuel plant growth. Regular use of Tropical Carbo supports vigorous, healthy plant development, which in turn helps establish a biologically stable aquarium and reduces the conditions that allow algae to thrive.

Flexible Carbon Supplementation

Tropical Carbo can be used as the sole source of carbon in your planted setup, or run alongside CO2 gas injection as part of a more comprehensive fertilisation programme. For best results, use it in combination with appropriate macro and micronutrient fertilisers, and dial in your lighting to match your plants' requirements.

Available Sizes

Tropical Carbo is available in a range of sizes to suit planted aquariums of different scales — from smaller, low-tech tanks through to larger, more demanding setups. Select the appropriate size from the options on this page to suit your tank volume and dosing routine.

A straightforward addition to any planted aquarium regime, Tropical Carbo gives you dependable carbon delivery without the complexity of pressurised CO2 systems — and the flexibility to integrate with them if you choose to go further.
