Back to Nature Modules Aquarium Modul(Basalt/Gneiss C)
Rock modules for individual aquarium and terrarium layouts. The modules C and T have been designed as filter modules, with an integrated water inlet. The open-topped filter modules are mounted in the tank free-hanging. Simply fill with filter media and insert a pump. These modules are also great for holding strong powerhead pumps, and they can be equipped with a magnetic holder so they can be mounted in the tank later on.
