I currently have an aquaclear 30 HOB filter on my 37g fowlr along with a protein skimmer and live rock. I have been using carbon and a filter pad, but I was wondering if this is good or if there is something I can put in the chamber for better filtration.
Also, I have been looking into reactors, what do they do and do I need one?
