8 Square Bio Rod 155mm

The Square Bio Rod is made of ceramic that has been heat treated at 1300 degrees for 60 hours. This tremendous amount of heat causes the ceramic to break its internal bonds thereby creating an extremely porous structure that has a greater surface area to allow very large bacteria populations to colonise.

Square Bio Rod can be placed in a suitable aquarium filter or sump with good water flow, ready for aerobic bacteria to colonise.  Once the bacteria has taken up residence it will process waste from fish and remove toxins liker Ammonia through the nitrification process.

Maintenance is simple, a gentle rinse in a little aquarium water is sufficient to get rid of any clingy solids. Bio Rods are not supposed to be clean.  You must never wash bacteria rich ceramic rings under in tap water as the Chlorine content will kill the bacteria.

Over time, the pores become blocked with debris and they should be replaced with fresh ones. The best way to do this is to replace 25% of the old one with fresh ones.
