Tropical Marine Centre is the official distributor of Tropica plants in Portugal and Spain. Plants are living organisms and, like everything else, they thrive best when they are treated with competent care and respect. Every year, Tropica cultivates several million aquarium plants in more than 130 different varieties that are exported to most countries in the world.

Important aspects to consider when choosing a filter media are: the surface area per unit volume, water distribution and flow characteristics when passing through the media, non-blocking properties, and a low weight per unit volume. For bio-filters the material from which the media is constructed should also have a micro environment suitable for colonisation by nitrifying bacteria.
