I wrote this recently for a publication -
So what is a planted aquarium? Put simply it is an aquarium that contains predominately live aquatic plants. The plants are often the main feature, along with the fish that provide essential movement, colour and interest. An easier way to put it – a “planted tank” has plants with fish and conversely, a “fish tank” has fish with (a few or artificial) plants. Planted aquariums provide many advantages over their non-planted counterparts. Plant growth uses up harmful toxins such as ammonia, nitrite and nitrate and heavy metals, through a process known as nutrient-uptake. Through photosynthesis the plants convert light and CO2 into oxygen, the most important element for all aquarium life. The plants themselves provide a sense of security and shelter to the fish. Finally a well-planted tank can look stunning and provide a beautiful slice of nature to any living space. Aquascaping, the art of decorating the aquarium with plants and décor is recently becoming very popular in the UK.
