Good Atomization Effect Reverse osmosis atomization tube, lower pressure requirement, finer atomization effect, only need pressure above 0.12mpa to get air out. The use of tubular atomizing core brings a larger atomization cover area compared with traditional ones.Eco-friendly The use of reserve penetration technology to diffuse CO2 can increase the dissolution effect and save the use of CO2, which is more environmentally friendly.Installation Steps Tighten the upper and lower shells with both hands, do not use brute force or hardware tools such as wrenches to operate; Do not tighten the air pipe locking nut too tightly, otherwise the air pipe will be damaged. Just a little bit tightness.Kindly Note The external atomizer will make a slight "squeaking" sound during use. This is not a leak, but the sound of CO2 gas after atomization.High Quality Made of highgrade materials, nontoxic, safe, energysaving and durable, for long term use. The design of a safe nut lock system can effectively lock the CO2 pipe and water pipe to prevent loosening.Specification:Condition: 100% Brand NewItem Type: Aquarium CO2 AtomizerColor: As Pictures ShownMaterial: PlasticInstructions:1 When leaving the factory, the atomizer is not tightened and needs to be tightened by the customer2 Do not use hardware tools such as wrenches to install or disassemble the product to avoid damage to the product3 The atomizer uses a accurate ceramic atomization tube, which needs to be completely saturated with water to achieve a good atomization effect. This time generally takes 24-48 hours4 The product needs to be installed with a check valve and bubble recorder before it can be used (the two need to be prepared by the user)5 The external atomizer will make a slight "squeaking" sound during use. This is not a leak, but the sound of CO2 gas after atomization.Note: The pressure reducing watch has a check valve function, and an additional check valve is required to allow the water body to flow back.Installation Steps:1 Tighten the upper and lower shells with both hands, do not use brute force or hardware tools such as wrenches to operate2 Do not tighten the air pipe locking nut too tightly, otherwise the air pipe will be damaged. Just a little bit tightness Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-DIMEANI official store
