Beetle Diffuser 30 mm

  • For aquariums 75-190 L (20-50 US gallons)
  • Preferred pollen-style diffuser for large aquaria or high-growth aquaria
  • Large surface area of diffuser disc ideal for high volumes of CO2 gas

The 30 mm glass Beetle Diffuser is a pollen style CO2 diffuser that connects to CO2 injection systems to easily disperse CO2 gas into the planted aquarium. The large surface area of the 30 mm disc allows for the diffusion of large volumes of CO2 gas, making the 30 mm Beetle Diffuser an excellent choice for larger aquaria or high-growth aquaria.

Compatible with 6mm (1/4") - Standard Airline Tubing. Suction cups included.

Rinse glassware with warm water. Attach suction cup and desired tubing (Compatible with 6 mm (1/4") - Standard Airline Tubing) to the diffuser.

To attach tubing to glassware, wet the inside of the tubing with water at the attachment point and carefully slide tubing over glass. The use of other lubricants is not advisable as these usually make the tubing slide off of the glassware too easily. To avoid breakage when removing tubing, do not pull tubing off of glassware. Instead, cut tubing carefully along the attachment length to release the glassware.

Mount your diffuser using the suction cup(s). It should be positioned low in the aquarium. When removing or repositioning the diffuser, pull by the suction cup(s) rather than the glass to avoid breakage.

Install check valve (not included) inline with tubing outside of the aquarium

Once securely mounted, turn on CO2. Observe bubble count and adjust CO2 to desired flow rate. Some of Seachem’s diffusers have a bubble counting feature. Otherwise a separate Seachem glass Bubble Counter is available.

A: A larger disc gives a greater surface area through which CO2 can be diffused, which can become important when trying to inject large volumes of CO2. Ideally, larger discs are used in larger or more heavily planted aquariums. Seachem provides recommendations for aquarium sizes on the diffuser and in the product description.

A: First, check that your tank has a volume CO2 and pressure on the line via any gauges. Second, check any bubble counter in line to see if you have flow of CO2. Next, check for any kinks, blockages, leaks in the line. Lastly, it is often required that the unit run 24 hours before flow of CO2 is consistent. Please allow 24 hours of run time to see if there is a long-term issue.

A: It is possible in time that organics and algae can work to clog the very fine pores that CO2 must flow through. Remove the diffuser and perform a thorough cleaning.

A: To clean a diffuser, generally soaking a unit in a very small amount of bleach and warm water overnight and then soaking in fresh water with Prime® or dechlorinator for a few hours is sufficient to clean away debris and algae. If this is performed without success a soak over night in water with vinegar may be necessary.
