Fish Crazy
It has been three weeks since I started my aquarium. The the power filter reccomends to change the cartridge every 2-4 weeks. My tanks is still going through the cycling process. I figured I would change the cartridge in four weeks. I don't have an underground filter. I am going to wash the old cartridge in the some tank water. I don't want to loose all my bacteria. Any other suggestions?
