GLA has the best diffusers hands down. This alluminum diffuser replaced my plastic atomic co2 diffuser. This model is certainly a step up in my co2 game. It has the ability to remove the ceramic stone to be cleaned or replaced. You dont need to buy 2 diffusers, just buy the extra ceramic tube and your set. One thing I liked about buying this diffuser from GLA was that they inspect each diffuser by hand to make sure all parts are accounted for. I purchased a knock off version is what looked like the same thing and when it arrived it was missing parts and appeared to not be properly assembled. The GLA diffuser arrived fully functional and now I have ample co2 mist entering my plant beds. Plants pearl like crazy by noon!

Review long overdo

I purchased this diffuser sometime during April of 2019
The diffuser I had received in the mail had been damaged due to package mishandling.
I contacted GLA via e-mail with photos immediately after arrival and Orlando did right by me and sent a replacement for it and some credit for plants that melted during the trip. The diffuser looks and feels durable because it is. Everybody looking at my scape eventually notices it, and it's not an eyesore. It aesthetically compliments my set-up, and stirs up conversation. Once they notice my glass lily-pipes, the next thing they see is this diffuser as their eyes follow the tubing, and eventually the rest of my shiny CO2 set-up. This diffuser will help make unsuspecting people assume you are a seasoned professional aquascaper. Everybody always asks or says "what is that for?" "It looks complicated" "Did you get it from the lab?" "Is this why your tank is so clean?" They are so impressed when I tell them "Those are not fake plants, they are real plants" (especially the red plants). Explaining basic plant biology to family and friends is something I have learned to do so well. My set-up is literally my visual cue to explaining why every piece of equipment is needed.

My experience with this diffuser has been great, never would of thought this piece of equipment would lead to helping make a great conversation starter this past year. I love explaining to people how my set-up works, as it's one of the few things I know about so well, It's truly gratifying.

Yes, I can probably buy something cheaper off of amazon or ebay that functions as well, but I rather have the support, service, and quality GLA provides for good looking products thus gladly pay the diff. as a premium. If the ceramic diffuser breaks during cleaning, I can just replace it and not the entire diffuser! I don't want to deal with cheap eye sores.

Wish I could post some pictures!
