U.P. Aqua Super Atomizer (large)

I bought this product for use with my pressurized CO2 system. First off, this atomizer requires a lot of pressure. The first day it fizzed perfectly and I was very happy with it. The next day it was fizzing about half as much as the first day and required more pressure. By the third day, it was no longer fizzing even with increased pressure high enough to start ballooning the CO2 tubing. I ordered this product twice and the same thing happened both times in the same amount of time. I was hoping that it was originally a defective product on the first one but that doesn't appear to be the case. I would NOT recommend buying this product.

Based on the previous reviews I purchased this atomizer in early April 2012 to replace and old Aquatek 3 in 1 diffuser installed in a CO2 pressurized system @ ±35 psi and it did not ouput as many fine bubbles as supposed to, first it took a very long time to start outputting bubbles, finally when the bubbles started to flow, they were big, like out of an air stone, thus not fully dissolving in the water column.

If you purchase this atomizer, I hope you get a non defective one since this has 5 star reviews.

And last but not least, Thank you Amazon for allowing me to return this item.

The diffuser produces a lot of medium and large bubbles instead of a fine mist of tiny, barely visible bubbles. The bubbles from this type of diffuser are supposed to be so tiny that they are hard to see individually and instead form a "mist". As you can see from the video it is not the case of this diffuser.

I replaced a "classic" CO2 diffuser (the type with a horizontal ceramic disk mounted in glass) with this one for my 125l aquarium. CO2 concentration dropped from 30 ppm to 16 ppm within 2 hours (I am measuring CO2 precisely with a professional device).

A good product in this category is the Green Leaf Aquariums Atomic Co2 Diffuser II (unfortunately Amazon doesn't carry it, look it up on youtube to see how it is supposed to work).

This product may be cheap but it will waste your CO2 and thus it will be more expensive in the long term.

I have a couple of these. One still works great, but the other developed a leak and now functions less than favorably by comparison. When they work, they're probably the best in terms of dissolving CO2 into the water column. I use a pressurized CO2 system FYI

This atomizer requires very high working pressure. It didn't get a decent flow rate until I got up to 50 PSI which is way too high for an aquarium setup, in fact my pressure relief valve trips at 51 PSI.

Would not recommend.
