Water Maintenance
In order for it to be used as a habitat for fish and plants in the aquarium, it must be prepared accordingly. Above all, compounds that harm the mucous membrane such as chlorine or heavy metals must be removed and the water hardness optimised. During ongoing use of the aquarium, metabolic products and organic water loads must be removed. Phosphate, nitrate and silicate concentrations in particular give rise to problems in freshwater and marine water aquaria, as they can lead to algae growth.
