Hello all, I'm brand new to this board and appresciate any help. I have a thriving 75 gal. salty tank w/ live rock, mushrooms, and healthy fish, but I want to set up a 29 gal. frewhwater community tank, and frankly, I'm a bit confused! Since I was a youngster I always thought that freshwater tanks were a simple add water + fish affair. But after some researh I've found that I may have missed quite a bit. So, I have a 29 gal. glass tank, and am serioulsly thinking about purchsing the Eclipse hood, 150W heater and an air pump/or PH for extra cirsulation. First, is the Eclipse hood a good idea? Second, I plan on putting in a moderate amont of substrate (1") or so of store bought gravel. So. after setting up, what are my options to cycle the tank? I would like to cycle with a fish (or 2 or 3 if needed), but I really have no idea what to start with. I would greatly appreciate any help on how to initally set up this system to let it cycle and then what livestock to initally add. Thanks all!
