CO2 Diffuser for Aquarium, Excellent CO2 Solubility Ensuring Vigorous Plants (30Dx300L)

there are many choices but for my CO2 setup in my planted aquarium, I prefer having a stainless steel diffusor and this one works great, does the job and allows for easy maintenance. Every 8 weeks to clean the diffusor disc, I let the disc sit it in small tray with 50/50 mix of Chlorox/water for a few hours, scrub and rinse off well, reassemble and the CO2 system is good to go for another 8 weeks again. I have had this unit working over 2 years now with no issues other than there may be some slight imperfections in the quality of the stainless but overall it works excellent and is easy to maintain.

The media could not be loaded.  This is my first time using c02, and this diffuser works great for my application; I have a 32 gal tank, with snails and fish. Instructions say to soak for three hours but it was at least 24 hours before I could get back to it after hanging it in the tank. After completing setup I turned it on and....voila!! Tiny bubbles! The instructions stated initially bubbles would be big but would settle down after a couple of days to tiny bubbles. I think the extra soak time probably prevented that situation. The only problem I have with this diffuser is the shape. I liked the look of the long neck with hook at the top but it doesn’t fit over the edge of my tank very well. My tank is Bio Cube and we’ve removed the hood and placed a Finnex LED light on the open top. The rim where the hood closed is pretty thick, and the hook of the diffuser isn’t wide enough to fit easily. It doesn’t bend easily and would possibly break if forced. I’ll use it until I get a different one, and will keep it for rimless tank setup later on. It does work well!

I've been using this for a few weeks now and it's great. It's way better than the one I got with my CO2 art kit that kept releasing huge bubbles. This diffuser releases very tiny bubbles and there are no leaks.

The media could not be loaded.  I went through a few diffusers before this one and they were all crap. I didn’t soak this in water before using it. It was spitting out half big bubbles, half fine bubbles for the first two days and now, on day three it is working well. I’m happy with it!

I love that this isn't glass, it's stainless steel. My first one I soaked for 7 or 8bhours before I hooked it up and although I got some fine mist from it, there were too many large bubbles for me. I contacted the vendor who sent a new one out immediately. I works perfectly.The only thing I don't like is it doesnt fit over the frame of my tank. I didn't want to "cut" a notch in it because I didn't want bits of plastic getting into my tank. I used a soldering pen to melt a spot just big enough for it to fit in.

My local independent aquarium supply house had a similar item but not as long (deep) so I had to find this online. My aquarium is 24 inches high and it is important to get the CO2 diffuser as far down in the tank as possible so the tiny CO2 bubbles get dissolved in the water before reaching the surface. This item works well with my new beer keg regulator and CO2 tubing. I can see the small bubbles coming out of the diffuser disc like it is supposed to. My one complaint about the seller is that they need to offer replacement discs at a reasonable price. I was able to buy a ten pack for about twelve dollars from a different seller on Amazon that fit this unit perfectly. I like to change out the discs when I clean the aquarium and clean them with a mild solution of bleach and water then rinse them and dry them for use another time. Would I buy it again ? Yes. I think it's a very good product that is attractive and WORKS properly.

Compared to all of the other diffusers I used, this is my favorite so far. The quality is great, really sturdy/solid and beautifully designed. I did not have to worry about putting on the CO2 tubing (the black rigid kind) and breaking the diffuser like some of the ones that are made out of glass. The bubbles are fine and evenly dispersed (some of my other diffusers have various size bubbles coming out of the ceramic membrane). No cheap plastic suction cup to hold the diffuser in place either. This works well with my rimless tank, but on my larger braced tank, I had to cut a small piece from the aquarium bracing for the diffuser. This is because the curve at the top of the diffuser can only support 1/2 and my aquarium + brace is 3/4 inch. Cleaning the diffuser is easy, just unscrew the top and clean the ceramic membrane without worrying about breaking anything.

I never set this diffuser up because it was way too short - I bought the size the site recommended for a 55g tank.3 stars because it is attractive and sturdy.3 stars because I never used it so I can’t leave a 1 because it could work beautifully.
