Hello everyone. I need some advice here. I have a 125 gallon that will be pretty well stocked with native fish. They are messy, so filtration is huge. I'll be running an FX5 and one or two Penguin 350s. The problem arises with media because I plan to keep a decent amount of plants too. I will likely fertilize as I don't want CO2. I've heard carbon takes out the fertilizers though. What should I use as media? Also, I've heard with heavier bio loads that fertilizers aren't as important. Is this true? Thanks in advance.
