Description

The inline CO2 Atomizer is arguably the most well known product used for CO2 diffusion, and is a firm favourite with planted aquarium specialists around the world. Designed for use with various filter size tubing, this CO2 diffuser sits inline between your filter and the filter outlet, ensuring that the CO2 has as much contact time with the water as possible. As a result, this atomizer dissolves CO2 very efficiently, and provides a stream of very tiny bubbles which exit directly out of your filter outlet. Furthermore, because it is kept outside the aquarium, maintenance is a very easy.

To use this CO2 atomizer, simply connect it, in-line, to your external filter outlet pipe and tighten the nuts. Connect your CO2 regulator to the atomizers CO2 input with air hose tubing and tighten the safety nut. The tiny bubbles that the atomizer produces will then spread evenly around the whole tank, ensuring a uniform spread of CO2.

Instructions

  • Inline atomizers are to be installed on the return / outflow tubing from a filter as the water is reintroduced to the aquarium.
  • Cut or replace your filter tubing with PVC tubing.
  • Push tubing on to each end of the diffuser.
  • Screw the retaining nuts back over the tubing to hold in place.
  • Unscrew the small nut on the CO2 inlet.
  • Feed CO2 tubing through the nut and onto the CO2 inlet.
  • Tighten the nut onto the CO2 inlet to secure the tubing.
  • Turn CO2 on, allow pressure to build within the diffser.
  • Adjust dosing / bubble rate accordingly.

    I've already noticed better plant growth since hooking it up. It fits perfectly with my 16/22mm hose, but heads up if you've got ribbed hosing, you'll need to swap it for PVC to make it fit on the tubing proplerly.

    Easy to install, it took me just a few minutes, and it's working fantasticlly.

    this product is truly fantastic, before watering it I had an ADA diffuser with which I delivered 7 bubbles per second to have a concentration of 21 mg/litre, the C02 bubbles were very large and many dispersed upwards, replaced with this fantastic atomizer, everything has changed wonderfully for the better, with only 4 bubbles per second I have the same result of 21 mg/liter of C02 concentration, very read more... this product is truly fantastic, before watering it I had an ADA diffuser with which I delivered 7 bubbles per second to have a concentration of 21 mg/litre, the C02 bubbles were very large and many dispersed upwards, replaced with this fantastic atomizer, everything has changed wonderfully for the better, with only 4 bubbles per second I have the same result of 21 mg/liter of C02 concentration, very small bubbles "a beautiful fog that is distributed in my 225 liters" thanks to the invaluable advice of the team I managed to install everything!! sincere congratulations!! highly recommended
