Description

This flat-bottomed glass CO2 pollen diffuser produces a fine mist of CO2 bubbles which improves CO2 diffusion in the aquarium water. Its extra large size makes it suited for aquariums up to 500L.

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.

    The first one had a bit of a chip out of the ceramic which was causing all the gas to escape from that one spot, I contacted support who asked me to send a video to show the problem, which I did, and they sent a replacement that arrived the next day. Not their fault and dealt with the situation well.
