How to Enhance Your Planted Aquarium with a DIY CO2 Reactor

To make a diy co2 reactor for your planted aquarium, you’ll need some pvc piping and a few other materials. First, cut the pvc tubing to size and then create a seal with silicone adhesive.

A homemade co2 reactor is an inexpensive and effective way to improve the health of your aquarium’s plants. The process of photosynthesis requires carbon dioxide, which can be difficult to maintain in a closed aquarium environment. By using a co2 reactor, you can supplement the carbon dioxide and promote plant growth. In this tutorial, we’ll go over everything you need to create your own diy co2 reactor. Whether you’re a seasoned aquarium enthusiast or a beginner to the hobby, this guide will show you how to create a functional and long-lasting co2 reactor that will benefit your aquarium’s plants for years to come.


Co2 is an essential element for maintaining a healthy ecosystem in a planted aquarium. It helps to promote the growth of aquatic plants by facilitating the process of photosynthesis. Co2 reactors come in different shapes and sizes, and there are several types of these devices.

Inline, hang on back, and diy are some examples of co2 reactors that you can use for your planted aquarium. Making a diy co2 reactor is not complicated as long as you follow the necessary steps. With a few materials, you can create a reliable and efficient co2 reactor for your aquarium.

It’s a cost-effective approach that provides plenty of benefits to both your fish and plants. So, don’t hesitate to give it a try and enjoy having a thriving and healthy aquarium!

Materials Needed

Making a diy co2 reactor for your planted aquarium requires some essential materials. You will need a plastic bottle, airline tubing, silicone tubing, a needle valve, a bubble counter, a check valve, and yeast and sugar for the mixture. The plastic bottle is the most critical material as it will hold the mixture.

Airline tubing and silicone tubing will connect all the components together. The needle valve regulates the co2 level, while the bubble counter monitors it. The check valve ensures the mixture doesn’t run back to contaminate the main water supply. You can buy all these materials from pet stores or online retailers.
