Hey all! I have begun setting up my aquarium and finished the hardscaping today. What I need help with is the filtration setup. This tank (Biocube 32) has a wet/dry filtration system built-in. The pic attached can show what it has. Please note that my setup does NOT have the balls. If this is something I need I can get them. But until then, this is my setup: The water is vertically through a ladder which can hold several types of filters, etc... The tank came with one type of filter cartridge that may be activated carbon?? The other steps on the ladder are empty and could hold various types of filter media. After it passes through this ladder, it goes through a filter pad of some kind and then gets pushed back into the tank. So my question is - setting up a freshwater and live plant tank, what filter media do I need?
