FX5's are not new all 3 sections of media have been removed heavily rinsed with hot water to remove any debri then it was placed in a large pot and boiled for 15 minutes at a time with a water change then put to boil for another 15 minutes totalling in 4 water changes and 45 minutes of high heat boiling then have left the media to dry in a well venilated room. I have gotten all new filter pads as well as the fine filter pads that go on top of the media. So what is the next step to get this tank up and running safely for my 7 peacock bass
