Item Type: CO2 Atomizer Material: Plastic Use: Fish Tank, Aquarium Carbon Dioxide Atomizer 1、[Less Pressure Needed] Using tube not sheet atomization core, larger atomization surface area, reverse osmosis, smaller pressure requirement, only 0.15mpa or more pressure can be discharged, which can provide finer atomization effect. 2、[Safety Locking System] This CO2 atomizer is designed with a safety nut locking system, which can effectively lock the CO2 tube and water pipe to prevent loosening. Use outside the fish tank, does not occupy space inside the tank. 3、[Installation] Please do the air tightness test on the two places of the arrowhead before connecting the water pipe, and tighten the upper and lower shells with both hands during installation. Do not use brute force or hardware tools such as wrenches to do so. 4、[Simple Appearance] Out tank CO2 diffuser, the more time the better the atomization effect. The appearance is simple design style, simple straight line and curvature, light gray and white. Can match the appearance of most fish tanks and aquariums. 5、[Bubble Observation] The later bubbles are very delicate, sometimes it is difficult to observe the bubbles from the front of the aquarium, you can observe from the side or control the CO2 level with the help of CO2 monitor to avoid over input of CO2.Manual measurement, please allow some errors.1 x CO2Atomizer
