Hello guys I have a few products to fill my fx6 and I was wandering which ones would work the best. I have zeo- carb and just straight fluval carbon, fluval ammonia remover, ceramic bio filtration(a ton of it), one came with the filter the other I already had, and a bunch of standard filter pads from Petco that you can cut.(this is all fluval brand except filter pad) What ones should I use in which layers? Thanks
