Second thing to set up system is how often you modify the river inside tank. When you frequently change the water inside the tank, the arowana fish is distressed with the change of water temperature as well as the irregular amounts of acidity of the lake. You need equipment that may help you to only change the river inside the tank only once or twice a week. That?s once the filter system enters the scene. Make sure that the filtration system are fully operational, otherwise it'll pollute water and poison the fish. I suggest you install both a and internal filter for better water circulation.

Germany is the world's first international auto show. The Frankfurt motor show, formerly known as the Berlin motor show, was founded in 1897 and moved to Frankfurt in 1951, with a rotation of cars and commercial vehicles each year. The Frankfurt motor show is the world's largest auto show and is known as the "motor Olympics". The Frankfurt international motor show, which is held every two years, is normally scheduled for about two weeks in mid-september. The exhibitors are mainly from Europe, the United States and Japan, especially European auto dealers. Frankfurt is in Germany and the main character is German business, which seems to be the same as the regional nature of the Detroit auto show and the Tokyo motor show. Germany is the birthplace of hyundai motor, the home of mercedes-benz, Volkswagen and audi, and the Frankfurt motor show is a great opportunity for them to strut their stuff
Space probe according to the detection of object is divided into lunar probe, probe and interplanetary spacecraft, small body such as a space probe to leave the speed of the earth must be large enough to overcome or get rid of the earth's gravity, realize the deep space flight. The probe orbits the heliocentric elliptical orbit (double-cut orbit) that is tangent to the earth's orbit and the planet's orbit, and may meet the target planet; Increase speed to change the orbit, flew to target the planet can shorten the time in order to ensure the detector fly the double track to the planetary orbits and tangent with the target when the target planets also run to it, must be chosen in the earth and the target planet at a particular moment of relative position detector. Detector can fly around the star, the use of planetary gravitational fields accelerate continuous multiple planets orbit the significant characteristic of space probe is, flying in space for long time, the ground cannot real-time remote control, so must have the ability of autonomous navigation; To fly outside the solar system, away from the sun, solar arrays, and nuclear energy systems; It is necessary to adopt special protective structure to withstand very severe space environment. Landing or walking on the surface of the moon or planet requires some special form of structure
