Is there an advantage to using higher light levels in low-tech tanks? Will there be a significant improvement in growth without CO2 injection?

Excessive CO2 can be stressful for livestock. These are ways to observe your livestock in Co2 injected planted tank.

CO2 Diffusers, Atomizers, Reactors, what are the differences between these devices and what should I use? What are the pros and cons of each method - this page discusses all these and more.

Gasping fish does not always mean you necessarily have good CO2 levels. This page explores the paradox of tanks with poor gaseous exchange, that suffer from both gasping fish and poor CO2 levels at the same time.

Why surface agitation and having good surface turnover, and good circulation in your planted tank is necessary to inject CO2 at optimal levels.

Read on to learn how to setup a CO2 system for planted tanks. Explains what each part does and how to connect up a CO2 system for the first time.

Read on to learn more about the benefits of CO2 for low light tanks.

What is a high tech planted tank? Should I spend the extra dollars for injected CO2? What are the pros and cons of going that route? This article discusses the considerations in depth.

The pH/KH chart is often used to read the CO2 level in the tank. However, many people get it wrong. If you are estimating CO2 levels using only pH and KH readings, you are likely to get an incorrect estimate of CO2 levels. Read on to find out how to read a pH/KH chart correctly.

A visually stunning freshwater aquascape without CO2 injection is more than possible. Using examples of real low-tech tanks, we analyse 6 strategies that will help.

Why do we need to inject CO2 into our planted aquariums when there is no CO2 injection in nature ?

How to measure CO2 levels in an aquarium - why drop checkers are a poor method for gauging CO2 levels and the best method for gauging CO2 levels is actually by directly observing plant growth forms.
