NilocG Aquatics | Intense Atomic Inline Co2 Atomizer Diffuser for Planted Aquariums Tanks (12/16mm(1/2") Tubing)

The media could not be loaded. I’ve bought this diffuser a few times throughout the years; I move a lot so I’m in and out of the hobby. I bought it yet again about 8 months ago and it was running well until recently when I noticed that the CO2 was pooling in my violet pipe, wasting the CO2. After evaluating the situation I made a few changes and now it’s running splendidly, better than before!1. I know several instructions indicate that the direction of the diffuser doesn’t matter, but it just so happens that I had it placed with the CO2 outlet up which means that the CO2 had to circle around to flow out. After changing it CO2 outlet down, it flows unimpeded through the outlet.2. I don’t have a check valve attached to the CO2 tube and there was some backup of water in the tube. This means that as the CO2 was leaving the bubble counter, it would hit a wall of water and pool in the tube, later leaving as a giant bubble rather than bubble by bubble. I’m sure the backup of water was due to the misplacement of the diffuser. Once I corrected the placement and cleared the backup of water, again, it flowed splendidly.3. Too low a flow from the filter. This aquarium used to have a betta in it so initially I didn’t want a strong flow. The betta is no longer in the aquarium and I noticed that the CO2 was pooling in the violet pipe, creating a bubble about 3 inches in length. I decided to upgrade my filter from a ZooMed Nano 30 (for up to 30 gal aquariums) to the Fluval 207 (for up to 45 gal aquariums). The stronger flow forces all the bubbles out of the violet pipe resulting in complete CO2 dissolution.Hope this helps anyone experiencing any issues!*I know my aquarium is overgrown and in need of maintenance, I take a more natural approach, don’t judge 🤪

I've been using this product for about a week. I purchased this diffuser to replace a in-tank glass diffuser I had purchased a while back before I had a canister filter. IMHO, the less equipment in the tank the better when it comes to aesthetics of a tank. It's easy to install with the supplied fittings for co2 and flow.It produces a nice fine mist but I was hoping for complete co2 dissolution and zero micro-bubbles in my tank, like some users have reported with this product. I will say when I first installed the product I did so about 8" away from my spray bar and got a lot of fine mist. When I moved it close to the filter (about 5" from the filter outlet connector) the mist had significantly decreased. I guess because the co2 has another 3' to travel before entering the tank, I'm getting better co2 dissolution.Also, I was able to drop my co2 from 4-5 bubbles per second to about 2-3 after switching to this inline diffuser. When I tried it at 1-2 I had zero visible bubbles/mist in my tank but my drop checker showed is was slightly co2 deficient. Hope this helps.

This performed much better than a glass diffuser I had puchased prior that came with only 4 or 5 holes open on the disc. Makes very small bubbles well and injects them into the filter output line. If you don’t have good flow around the glass one the co2 goes right out the top, so better utility. I paid about $40 and I’ve seen them for half of that. Though I’m a firm believer in you get what you pay for.

This diffuser only works if you have a canister filter. You cut the output tubing and insert the device so it is inline with the return flow. It is best to do this close to the canister filter so that the micro-bubbles can dissolve even further.When running, there is a fine mist barely visible in the water that appears to be way smaller than the bubbles from those glass lily cup diffusers. I have the Eheim classic 2213 canister filter and the 12/16 mm size fits perfectly.In my setup, it lasted around 5 months before I needed to clean it, which can be done in a weak bleach solution soak for 24 hours. I wound up buying a second one so I would have no down time on my canister filter or CO2 injection.The only disadvantage is its high price, as its just a piece of plastic with a ceramic insert.

This Product: When first connected the product works. The problem is that as soon as the solenoid cuts off, the product fills with water. The next time the solenoid turns on the product fails; unless the water is manually cleared. Not much good if you need CO2 in the tank daily.My System: Eheim canister filter with 12mm return back to tank with a connected 5lb CO2 tank using a Titan Control regulator. There are zero leaks in the system and PSI is well over 50. I have a CO2 rated back-flow check valve right at the infuser so there is no water in the line. CO2 rated hose is used from the regulator to the diffuser.

The media could not be loaded. First, the good: This thing puts out the finest mist I've ever seen. I've used two different in-tank diffusers and a different in-line diffuser, and all had large enough bubbles they would not all dissolve and I'd lose some bubbles at the surface of the water. With this I was able to turn my CO2 down by about 30% due to how much more effectively it dissolves the CO2. The mist is TINY. Bubbles so small they did not even float to the surface, they just float around until dissolved. In fact I almost gassed my fish and shrimp the first day. Even my Christmas moss is pearling!On to instructions. There are a lot of reviews saying the screw-down fittings do not fit over the hose. They are not supposed to. There is a specific way that many aquarium hose fasteners work and it's probably the reverse of what you think.Check out the pictures I added. The first one shows that one side of the threaded clamp has a tapered edge. You want this facing away from the diffuser. Screw it all the way down, WITHOUT the hose in place. Then push the hose on as far as it will go. Then, turn the threaded clamp as if you were trying to loosen it from the diffuser. Doing this will effectively TIGHTEN it over the hose since that taper pushes over the tubing, squeezing it tightly against the fitting. That's all you need to do. No extra clamps needed!
