In addition to its antibacterial properties, the four-layer antibacterial water tank is stronger than single-layer and three-layer polyethylene tanks because it has four layers. A black layer is placed between these layers to prevent light from penetrating into the water tank. This prevents algae from growing inside the tank, so the water will retain its taste and smell. Preventing the growth of algae, which is also known as a food source for bacteria, makes the process of dealing with bacteria more effective.
