According to the Aquatic Gardeners Association, a paludarium is an “aquarium with above and below water aquascaping.” This is not to be construed, as is […]

Some Final Thoughts on Carbon Dioxide

by John Tullock Carbon dioxide is essential to plants, but a carbon dioxide system is not essential for some planted aquariums. Tanks with slow-growing, low light plants such as ferns and many species of Cryptocoryne do just fine without supplemental carbon dioxide. On the other hand, a large, brightly illuminated tank filled with fast-growing stem […]

Carbon Dioxide Part Two: Estimating Concentration

by John Tullock In Part One last week, I discussed the importance of carbon dioxide (CO2) in the planted aquarium, and described several types of equipment used for adding CO2 to improve plant growth. In this post, I will discuss how CO2 concentration can be estimated when the pH and alkalinity of the aquarium are […]

Carbon Dioxide: Part One

by John Tullock All plants need four basic things to survive. These are: sunlight, carbon dioxide, water, and minerals. In the aquarium or paludarium, water is never in short supply. Thus, light, carbon dioxide, and minerals become the important factors limiting plant growth. This series of posts will examine the role of carbon dioxide and […]
