Description

This flat-bottomed glass CO2 pollen diffuser produces a fine mist of CO2 bubbles which improves CO2 diffusion in the aquarium water. Its small size makes it perfect for small or nano-sized aquariums.

Instructions

  • Because the item is made from glass it is inherently delicate, and extra care needs to be taken when fitting it in the aquarium. It is highly recommended that the tubing is first warmed in freshly boiled water to soften the tip when pushing onto the diffuser inlet.
  • Position just above substrate below the filter outflow. This will ensure the bubbles enter the flow of water from the filter and hold the CO2 in suspension for longer, increasing CO2 diffusion levels.

    Great quality glass and nice small design, seems to be working very well with my DIY yeast CO2 system and producing very small bubbles. The email they sent with advice for safely attaching to fittings was welcome.
