So I'm running a Fluval Aquaclear 110 HOB. Just did my 3 months chemical on my filter. I figure the chemical filtration bag that comes with it, is most likely done filtrating by now lol. SO I was looking for any suggestions to either a chemical filtration to add? or if anyone suggests just adding more media or maybe an extra sponge? I do have a pretty big piece of spider in my tank just a fyi!
