9 Spiral Glass Pollen CO2 Diffuser - For Aquariums up to 180L
 
 

Key Facts

  • 9 Spirals inside diffuser.
  • Diffuser Body length ~12cm.
  • Ceramic disc diameter ~2.5cm.
  • Recommended for aquariums up to 180L.
  • 2 x Suction Cups included.

Description

These beautifully styled spiral diffusers look like something from a mad scientist's laboratory, and certainly create a focal point for your aquarium. You can see the CO2 spiralling up the coils inside diffuser, creating a memorising effect.

The CO2 is then forced through a ceramic disc, which creates a fine mist of CO2 bubbles, which then diffuse in the aquarium water.

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.
  • When the diffuser is first connected you may find the CO2 escapes from a small hole at the bottom of the spirals. Rest assured, the hole is meant to be there and this is normal behaviour. Once the diffuser has been submersed in the water for a few days, the chamber of the diffuser will fill with water and the spiralling effect will begin.

Works fine but doesn't fill up to the top with water as I thought it would, so you have to count the bubbles coming up from the small hole at the bottom, seems to do the job the same though Works fine but doesn't fill up to the top with water as I thought it would, so you have to count the bubbles coming up from the small hole at the bottom, seems to do the job the same though

Not very efficient and difficult to purge the air out of. Does much better if positioned directly under the filter outflow. Gets covered with algae quickly.

Looks cool in my tank and does the job well only drawback would be the inlet points down, would be better to point up which would prevent air hose kinking ...

Great quality, looks brilliant especially being glass, taking it's time to fill with water as been in the tank over a week but is only one third full, sure it will get there eventually.
