Tank maintenance is very simple : occasional trimming, feeding, water top off. No Ferts, No CO2, no water change, no gravel cleaning.
I first had a 20 gallons high tech tank. But i got tired of the needed maintenance, tank was unstable, regularly plagued by algae without any reason. It could not run without CO2 and regular water change were needed to keep algae into check.
I discovered then Diana Walstad's book by reading some topics here and decided to give it a try after we moved. So far, i'm extremely happy with the tank ! It's so stable, i can really enjoy watching my tank as a peaceful slice of nature.
