If I’m at the point where I can just scrap a second aquarium to start over, how do I do it? Wash everything out? Fake plants, rocks and statues and then buy new sand? Then how do I clean the filter? Bleach it and buy new media as well as the sponge filter? You can’t bleach a sponge filter right? Or should I just buy all new and be safe so the ich doesn’t transfer to the new tank?
