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.
The rapid development of air filters is closely related to the development of military industry and electronic industry. In the first world war, the use of various chemical agents, asbestos fibre filter paper as the smoke filter layer of military gas masks came into being. The glass fiber filter medium is used in air filtration to obtain a patent in the United States in October 1940. In the 1950s, the United States studied the production process of glass fiber filter paper, and the air filter was improved and developed. In the 1960s, HEPA filters came out; In the 1970s, the filter paper of fine glass fiber was used as the HEPA filter of filter medium, and the filtration efficiency of particle size of 013 micron particle diameter was 99.9998%. Since the eighty s, with the emergence of new test method, use evaluation to improve and to improve the filtering performance requirements, found the HEPA filter there is a serious problem, and he had a higher ULPA filter performance. Countries are still working on it and expect more advanced air filters soon
