Biorb Service Kit The filter cartridge works like a waste bin, trapping dirt, once full it should be thrown away and replaced with a new one. To keep your biOrb or biUbe at its best, this should be done every 1-2 months. A partial water change of 30% should be carried out at the same time.
I had bought this product in the past and it worked well and easy to install. If you wish to recycle the parts, I have found you can rinse the foam filter ring well, pour a little clean charcoal filter material in the plastic ring,replace the foam ring and fill, and way cheaper and no throw away.
