Keep your Bio Media in a compact holder in your sump. Capable of holding 2 or 4 Bio Spheres in a compact space while allowing water to flow freely through all sides.

Optional legs can be glued in place with cyanoacrylate glue such as Crazy Glue (Not Included) to lift the holder off the ground giving more flow underneath the unit.  


2 Block holder dimensions are 3.25" x 3" x 3"

4 Block holder dimensions are 5.75" x 3" x 3"

Keeping your bio blocks like this will greatly increase efficiency when compared to sitting on the bottom of your sump. During a water change just quickly pull the holder out of the tank and give it a swish to keep detritus from settling.

These are printed in PETG so they are reef safe.


*Maxspect Bio blocks are sold separately
