If While gravel filter is insufficient at least my favorite kind, I suspect that the "… bubbles are annoying at the top of the tank at all times …" can be sparkling wine to put unwashed hands in the water, no air pump. I have 0 experience with 1 gallon. tanks, but here is a link to the smallest filter I could find at Petco. http://www.petco.com/product/12148/Red-Sea-Deco-Art-Nano-Filter-and-Replacement-Pads.aspx not the best on the market, but I'm sure that beats under the method gravel.
