    Nice diffuser.

    Posted by Frederick Jones on 7th May 2024

    I really like this diffuser as it gives me a very fine mist of co2 bubbles. It is a bit pricier than most but nice to look at and works great. Only issue I have is it’s a bit bigger than I wanted because I have a shallow tank at 7” deep so the long elbow bend is buried in the soil. Will probably switch to an atomizer soon but keep this as a spare just in case. Happy with my purchase.

    Acrylic CO2 diffuser

    This tiny CO2 diffuser creates a lot of superfine micro bubbles and it works even if a bit of algae grows on it. A good buy overall.

    Acrylic CO2 diffuser

    Posted by Nita on 19th Aug 2023

    This diffuser creates very fine bubbles. It is going more than a week churning small bubbles - other diffusers generally clog by this time.

    So I finally decided to get a co2 system for a planted tank I had started and let me tell you….. the growth after the addition of CO2 was explosive to say the least. The dual stage regulator/solenoid/needle gauge are all top of the line. Well worth every cent.

    First diffuser

    Posted by Jordan on 19th Apr 2021

    This is the first diffuser I’ve owned. It runs quite well at 30 psi but had trouble bubbling up when the co2 was turned on in the morning with anything under 30 psi. This is common for ceramic disks. Overall provides the aquarium with very tiny bubbles, working great.

    Super fine mist great quality

    Posted by Brian Holt on 29th Jan 2020

    This diffuser creates a super fine mist like no other white ceramic disc diffuser you will ever see. I find it best to use GLA soft co2 tubing with this diffuser because it makes installation much easier. Otherwise I could not ask for more from this diffuser. It even comes with an inline check valve in the box along with a syringe. :) Happy customer!

    Small, Simple, Fine Mist

    Posted by Jake Snyder on 8th Aug 2019

    This was an easy to install product. The end seems a bit large, and it was tough to install the CO2 tubing (purchased from GLA) over the end (I tried heating with water). It puts out a fine mist (powered by a GLA regulator) that seems sufficient at distributing CO2 throughout the tank. I’m not sure why it shipped with a small syringe. Maybe some directions would improve this product.

    Works Great

    Posted by Ken on 30th Jul 2019

    This is my first diffuser for my aquarium and is being powered by my new GLA-GRO1 (Everything I ordered from GLA was packaged very well and arrived without issue). Setup was a breeze and as a bonus it comes with an inline check valve. Bubble mist is really fine with bubbles easily being carried to all parts of my tank. I will also add that making the necessary CO2 tube connections was greatly simplified by first heating the tubing to make it more pliable.
