Description
【AUTOMATIC PRESSURE RELIEF】The safety valve automatically relieves pressure when the pressure in the bottle reaches 70kg/cm. It is safer and lighter with a new stainless steel gas cylinder. Do not invert the steel cylinder or tilt it. 【CONTROL THE BUBBLE SPEED】You can use the fine-tuning valve to control the speed of the bubble according to the size of the home aquarium, thus controlling the carbon dioxide content in the aquarium to ensure healthy growth of the organisms in the aquarium. 【PHOTOS
