Media is escaping and being discharge to waste when cleaning my Eazypod

This can happen if the outer steel mesh is slightly out of position, this sometimes happens during transit, remove all of the media from the biological chamber (this will stop any media becoming trapped when you tap the mesh back into place), with a large flat-headed screwdriver and hammer, gently tap the mesh back into place so it is flush with the base of the filter. Replace the media and it should now work perfectly.
