Liquid Carbon 1000ml by Aquadip will help aquarium plants to thrive
Liquid Carbon (CO2)
Liquid Carbon (liquid CO2) helps plants to grow healthily with good colouration. When plants are growing well this can outcompete algae in tropical aquariums. It is also useful to fight black beard and hair algae. Add Aquadip Liquid Carbon (CO2) every day for best results. Choose if you would like a dosing cap or not (there is no charge for dosing caps. However, as they are plastic, please re-use if you already have one). Bottle pumps are available instead of dosing caps if you prefer.
