Thanks for all the great feedback from everyone!!! From looking around it seems like if I decided to go with the Aqua Clear pump, I would need to get an under gravel filter to boot. I have a 10 g hex on my desk (w/about 10 very small tiger barbs...beautiful!) that has a bio-wheel which seems to be doing great, so as of right now, unless someone can sway me, I'll probably roll with the Penguin 350 Bio-wheel. Would I really need to get 2 350s since my tank is only 55 gallons (seems a little excessive), or just one rated for 75 gallon tanks, or 2 150s, each rated for 30 gallon tanks. On the note of potential failure of a pump, I thought I understood the Emperor to have 2 separate pumps, so if one fails, the other is still running (short of a power outage). See what you think

...does that seem exclusive to the Emperor series and not the Penguin?
Stocking:
I'm looking at doing an African Cichlid tank. I know people are hardcore against LFS, but Petco ran a sale on premium African Cichlids ($3 for about 2 in!!!) and I have a raincheck for about 13. I also got my 55 from their dollar a gallon sale...sweet! I really wanted to make a tiger barb/cichlid tank, which most people would say no I think, but I've heard of things like angelfish and cichlids....any thoughts?
Cleaners: So what's the word with what type of fish to clean a tank. I have a Pleco in a 20 doing great, but I have heard cories, cats, and loaches are other options...what does everyone like in a combo with cichlids?
Substrate:
I really want to keep this one natural, so I'm definitely looking at doing some holey rocks, driftwood, and broken pots, courtesy of Wal-Marts garden shop, but are there any good websites for affordable natural substrate?....I'm a poor college kid. Also, what would I need to keep live plants in the 55, and are there any benefits. I heard that you can't run a pump with a current across live plants (seems kinda wrong if you look at nature), any truth to it? And also I have heard both sides (good and bad) of putting some form of an aerator in a tank with live plants...what do you think? What kind of lighting and maintenance is necessary?
Stand:
Being very short on $$$, I kinda figured it would be cheaper to build my own stand, that way I could also customize it to my liking. Know of a website or anything to get free plans and diagrams to build one?
Thanks,
Zack
