Hi! I am brand new to this board, i will hopefully soon be starting an ostopus tank of my own, although im kind of confused on what I need to do this. And yes I have read "ceph care". I was wondering if I should buy a sump or just build my own. Any ideas would be greatly appreciated. I am going to buy a 55 gal. tank. Oh yes and by the way this board is awesome! Thank you for your input ahead of time.
