Internal Filters

Internal filters abide by the same principle as external filters, except the filter is housed inside the aquarium. The function of the internal filter is to maintain the ecological balance in the aquarium which nature does by micro-organisms (bacteria). These transform organic waste into simple inorganic substances. We carry internal filters of all sizes. We carry all the major brands including JBL, Hydor, Juwel and Eheim.
