Bio Brick Holder Quad Vertical

Made to help tidy up those sumps and maximise flow and contact time with your media, these quad biomedia brick holders, securely hold a variety of bio media blocks (100x100x25mm).  With raised feet they allow flow under and around your media for optimal conditions for your nitrifying bacteria.  These are for stacking your media blocks vertically on top of one another allowing you to maximise your biomedia in a smaller footprint.

Made from aquarium safe PETG filament.
