Why Use Liquid Carbon?

If you’re wondering how to make liquid carbon for your aquarium, it’s actually quite simple. But why should you consider using it in the first place? Liquid carbon, also known as liquid CO2, is a popular alternative to injecting pressurized CO2 in planted aquariums. It helps stimulate plant growth by providing a source of carbon, which plants need to carry out photosynthesis.

Liquid carbon can also help control algae growth by outcompeting it for nutrients. Plus, it’s easier to use and requires less equipment than pressurized CO2 systems. To make liquid carbon, you can purchase commercially available products or create your own DIY solution using common household ingredients like yeast, sugar, and water.

Just be sure to follow proper dosing instructions and monitor your aquarium’s pH levels, as liquid carbon can lower the pH over time. Overall, liquid carbon is a great option for planted aquarium enthusiasts looking to promote healthy plant growth and keep algae at bay.
