Low-tech aquarium (without CO2 injection)

A planted aquarium managed without CO2 injection, with moderate light and minimal maintenance.

Diana Walstad's method is the reference for extreme low-tech. The photoperiod is 6-8 hours.

The advantage is stability and low maintenance. Ideal for those who want a beautiful aquarium without dedicating hours to it every week.
