Fill and drain system
Fill & Drain system is our most simple aquarium rack solution. There is not affiliated any filter system for this type of shelving, just a pipe that connects the rack for fresh water and sewer. You use this option if you want to use bottom filters or internal filters in your aquariums - of course in combination with a system that gives you water and drainage in each aquarium. The Fill & Drain system can also be used in connection with a larger central filter unit.
