Aquariums can get dirty quickly. It's not a surprise, though - all those plants, fishes , corals, food products, vitamins and supplements in just one place can sure accumulate a lot of dirt in a short period of time. Because dirt collects fast, you have to be faster with cleaning up. Luckily, you don't have to do it manually all by yourself. A lot of tools are available to you, one of which is the JBJ 28 Gallon Nano Cube Protein Skimmer Kit from www. petstore. com, a skimmer that skims off the thin layer of protein that forms on the water surface. The principle behind a skimmer is simple: It's a small cylinder with an air pump which draws in water. Then, the air stone inside it creates bubbles from the drawn water. The protein residue sticks to the bubbles' surface, so when the bubbles enter the cylinder, the residue does, too. When the bubbles pop, the residue remains inside the cylinder and is then collected in a cup inside it for later disposal. The JBJ 28 Gallon Nano Cube Protein Skimmer Kit does all that automatically and regularly. It is easy to install inside your aquarium. It is already equipped with a removable cup used for collecting residue, and also comes with its own air pump and air stone. As a bonus, it also has an air tube to improve oxygenation in your aquarium.
