How to choose a marine ornamental fish tank? Please also specify the equipment in the storage tank. I'm going to buy a seawater tank with a length of 130. I want to raise clown fish. Thank you!

Oxygenating equipment. This is very important and must be equipped, especially if the fish tank is small or some colorful high-oxygen fish are raised. In addition, pay attention to adjust the inflation in winter. If the inflation is too large, the water temperature will drop and the fish will catch a cold. Filter. Generally, submerged filter, bottom filter and sponge filter are commonly used. Upper filtration and submerged external filtration are the most commonly used and the cheapest; It is troublesome to place the bottom of the water and it is not easy to clean it, but it is best to use this aquatic plant, which is generally more expensive; Sponge type, also called air filter, is attached to the air pump and must be equipped for raising colorful fish. Lighting equipment. Incandescent lamps cannot be used, which will affect the viewing effect. There are three main types of lamps: fluorescent lamps, the most common and cheapest; High-pressure mercury lamp has good effect and saves electricity, but it is too expensive; Halogen lamps that are not commonly used are very energy-saving, but they are not durable. Beginners had better use fluorescent lamps to raise fish. Warmer. Nowadays, it is very convenient to use controllable temperature heating rods. There are two kinds of immersion heating rods and non-immersion heating rods. Diving heating rods are also called diving heating rods, so it is more reliable to buy imported ones. In addition, a thermometer should be equipped to know the temperature of water. There is a big place to buy fish in Madian, Beijing, and many merchants are very enthusiastic. You can go there for consultation. When I was collecting rainwater, I asked there. Opposite the old IKEA in Madian, it is also sold in the north of CCTV building. There is also a Laitai flower in the northeast of Yansha, but there are many seawater tanks in Madian.
