Description

This flat-bottomed glass CO2 pollen diffuser produces a fine mist of CO2 bubbles which improves CO2 diffusion in the aquarium water. Its large size makes it suited for aquariums up to 250L.

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.

    This diffuser works well and also looks good I think, it is however very fragile and the instructions need to be followed with respect to warming the tubing prior to fitting.

    I love the design and looks very neat. The first one I got was leaking around the ceramic but a quick email and a video and co2 supermarket sent a replacement which worked fine. I guess I was just unlucky. I love the design and looks very neat.

    A decent size and seems to do the job. Very fine bubbles released and will fit neatly into a tank corner. Just be a bit careful with the tubing A decent size and seems to do the job. Very fine bubbles released and will fit neatly into a tank corner. Just be a bit careful with the tubing

    Looks fantastic in the tank. Comes with two suction cups on the 250L version that allows you to place in the corner of your tank glass. I soaked mine in some warm water to loosen the suction cup plastic to make it easier to apply. Very happy with it. Looks fantastic in the tank.

    Very good on diffusion of co2 and being glass it doesn't stand out too much. Very good on diffusion of co2 and being glass it doesn't stand out too much.

    Great company to deal with. Pity I could only give them 5 stars. They went to great lengths to help me in selecting the correct equipment for my set up. All my future CO2 supplies will be from them. Would I recommend them yes, yes yes Great company to deal with. Pity I could only give them 5 stars.
