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 🤪

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!

Worked great in my tank.

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.

I’m using Marineland 12-16mm (1/2) tubing and the fitting that secure the line DO NOT FIT because they’re too small. I saw a lot of other users having the same issue and installing it anyway without tightening the tubes onto the threading. Felt brave and also tried that and woke up to 5 gallons of water damage on my floor. My god do wish I could go back in time and avoid this product.

For its compact size, j was a little hesitent to see if it would really work and be leak proof. And it sure works well. The co2 coming out of my output line is very fine. The power of my filter also helps get the co2 circulated through out the entire tank. So less co2 is needed over all.Only one small inconvenience. Which could also help in a weird sort if way. If you install this device so the co2 inlet is down, water will seep into the chamber and covers the co2 inlet. However when co2 is turned on, it forces water back through the defussion barrier so it will empty to a point. Water will always be over the inlet and you can watch your co2 bubbles flow through the little bit of water in the chamber. So its kinda like a simi accurate very unofficial bubble counter built in. Neat.Also, make sure you install this device as close to the outlet of your canister as possible. So it will bave more tube to travel and give the co2 a chance to diffuse even more.
