I plan on setting up a 5 gallon tank once I get a hood and a heater for it. I have a small 7w heater, but I assume that it's not good enough. I will want to divide this tank, and probably only have fake plants in it with a gravel bottom. I really don't know anything about cycling. Luckily, my 10 gallon cycled itself before I knew what the cycle actually was. I haven't messed with the cycle since then, and just do weekly water changes.
So, with the 5 gallon, how/where would I start with cycling it? I would almost rather not do a fish-in-cycle since I don't want to mess up and kill the fish. I would also like to add both fish at the same time to the tank after they've been quaratined. I have 2 or 3 HOB filters that I've used over the years. The HOB I have in my 10 gallon has a bio-fiber thing in it which I assume is a good thing. I'm not sure if my other HOB filters have that. Do I need it? I also have a tetra whisper 2-10i power filter that does have some sort of bio-fiber thing in it. Which type would I need?
How many water changes would I do per week, and how much would I change?
Anything else I need to know/think about?
