need help buddy got a ufo 550 corner tank need to understand about filter system so it sinks in properly any advice would be grateful many thanksCarbon adsorbs stuff over time and is not normally necessary in an aquarium. I usually suggest throwing the carbon away and just replacing it with a sponge. You can buy sponges for various filters and use a pair of scissors to cut it to size. Sponges last for years and you simply squeeze them out in a bucket of tank water every few weeks and re-use them.
