- Small size, large capacity: The bottle body is made of thickened SUS304 stainless steel. Each time, 400g of raw materials are added. The gas storage capacity is equivalent to 4.8L, but the size is only 2.4L, occupying no space. The gas usage time is also longer. It is an excellent choice for medium and large-sized aquatic tanks.
- Complete accessories: Included are: L-sized fine filter (this is a must-have item for efficiently dissolving CO2 into water); reverse flow valve (a must-have item to prevent water from flowing back); water filling electromagnetic bubble counter (used with a timer, CO2 can be turned on and off at regular intervals); water filler (makes it more convenient to replenish water for the bubble counter); funnel (exclusive large diameter, less likely to get clogged and smoother). Note: The package does not contain raw materials. They need to be purchased separately.
- Low-temperature electromagnetic valve with quick plug-and-unplug interface: The working temperature is lower than body temperature, not hot to the touch, easy to plug and unplug, and can be flexibly rotated.
- Stainless steel material: The pressure reducing valve, filter core, bottle body, etc. are all made of SUS304 stainless steel, durable.
- Exclusive triple drying and filtering design, which can significantly reduce the failure rate of the electromagnetic valve.
