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.

A visually stunning freshwater aquascape that does not have injected CO2 is more than possible. Using examples of real low-tech tanks, we analyse 6 strategies that will help.

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

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.

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.

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

The pH/KH chart is often used to get a reading of CO2 levels in the tank. However, many folks go about this the wrong way. If you are estimating CO2 levels using only 1 pH reading - then chances are you are getting an incorrect estimation of CO2 levels. Read on to find out how to read pH/KH chart correctly.

Is there any advantage to using higher light levels in low tech tanks? Will there be 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.

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.

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.
