Earlier this month we were discussing the possibility of Non-CO2, Low Light Aquascapes. In sum, several of members posted some great aquascapes that proved that it was possible to make a beautiful, lush planted aquarium under these conditions. Now begs the question, which type (low tech or high tech) is better for aquascaping? Now, the definition of a high tech tank and a low tech tank can be arguable. To begin the discussion, low tech tanks are not necessarily classified as without CO2 injection or having low light. I define low tech tanks by how much light is put over a tank, generally at 2.0 watts per gallon (wpg). They can consist of automated autodosers, C02 injection, etc. but in truth most low light tanks won't need them since plant requirements are not as demanding. High tech tanks are everything above 3.0 wpg. Light drives plant growth, subsequently increases the demand for regular fertilization and high levels of consistent CO2 injection. Here we see the need for near daily attention from the hobbyists to feed the plants, wipe away algae, and perform waterchanges. Discussion Questions How do you define High Tech and Low Tech Planted Aquariums, and which one is ultimately better for aquascaping? Should we be recommending one type over the other to new planted aquarium hobbyists? -John N.
