ITEM NAME:1X(Aquarium Co2 Regulator Tank Live Plant Flow Pressure Control Check ValveG6I8) 1X(Aquarium Co2 Regulator Tank Live Plant Flow Pressure Control Check ValveG6I8) 1X(In order to achieve better aquaculture effect,we have to add carbon dioxide in the water,so that the aquatic plants can grow more quickly,the colors can be more vivid and the leaves can be thicker.The main purpose to add a pressure reducing valve is to reduce the air supply pressure and stabilize it to a fixed value so as to obtain stable air supply power. The double tables show the pressure and output pressure in the cylinder.The bubble counter can intuitively and precisely control the air amount,and the regulator valve is used to regulate the air output. Output Voltage Display:60-100pis is the most secure and stable value.Bottle Pressure Display:When the bottle pressure is 0,it means that inflation is needed. Anti-return Bubble Counter:You can observe the bubble quantity with this counter and regulator.And water should be added to avoid water flowing into the decompression table. Precision Regulator Valve:It can be used to precisely regulate the air output flow and adjust the sensitive output stability. Color:picture color Material:aluminum alloy Package Contents: 1*Aquarium CO2 regulator)
