First, welcome to Fish Lore Wolfman
I am glad that you're cycling your tank first, before adding any fish to it. I presume you're informed about the cycle, correct? Can you please list your
ammonia reading? If it's only a week old tank and both nitrite and nitrate equal zero, maybe you have at least ammonia in there by now. Your tank will be ready for fish when ammonia and nitrite equal zero. Nitrate, on the other hand, will be showing. But please remember to stock your tank gradually once the cycle is finished, so that you won't have any sudden ammonia and/or nitrite spikes (which can happen if you add too many fish at once, especially to a new tank).
I agree with Tumbleweed on the test strips. I mean, you're free to use them, but if you want a really good and reliable testing kit, I'd recommend for you to get Aquarium Pharmaceuticals Freshwater Test Kit. That's all I ever use and never been disappointed with this company - I love it. The test kit is $30 at my local fish store, but if you go to Big Al's Online, you can buy it there for LESS THAN $15 - big difference huh? LOL

If you want a low-maintenance tank, do not overstock your tank and do not get too large fish (and too many of the large fish) as for your tank. If a tank is lightly stocked, you have smaller and less frequent water changes to perform, and yet your nitrate level stays low or at 0. My 10 gallon tank is very lightly stocked, and all I have to do there are 25 - 30% water changes every two weeks to keep nitrate at 0. (Though I perform 25 - 30% water changes once a week.) Also, do not overfeed, as it will increase your nitrate faster and therefore you'll have more or larger water changes to do.
An excellent algae eater for a 55 gallon tank would be a Bristlenose Catfish, or a Siamese Flying Fox / Siamese Algae Eater (make sure its scientific name is
Crossocheilus Siamensis, as this algae eater is often confused with other algae eaters that are not true Siamese algae eaters).
