Rhinox NEW Nano Carbon Dioxide CO2 Diffuser Glass Reactor for Aquarium Tank Plants Spiral

This CO2 diffuser is decent for a beginner trying to setup a planted aquarium. It works but not great.One issue is that, the one I received, allows a few large bubbles ~0.5-1 mm to pass through even at low pressures/low flow rates. These bubbles rise to the surface too quickly and don't give enough time to allow CO2 to diffuse into the water. It seems the diffuser material and the interface with the glass sidewalls could be manufactured better to prevent this from happening.My second complaint is that it's difficult to connect it well to standard aquarium tubing. On my first several attempts, the tubing kept falling off after several hours. Finally I decided to run the tubing under hot water and push the tubing very forcefully over the ring neck of the connection. Mind you, since this is glass, I was quite concerned about breaking it and cutting my hand. Now, it seems to be forced on securely and hasn't fallen off since, but it was a lot more effort than I was anticipating.

This is a pretty diffuser, but the bubbles stop coming out of the middle too soon after you start using it. I tried soaking it in the bleach solution (which I found to be scary--how do you know you got it all out?) but it didn't help. And, the tubing wouldn't stay on. I tried the other diffuser by Rhinox and still had the same problems. I eventually went to the cheap black one by Fluvall and it works perfectly. A waste of money.

The diffuser works just fine. Not only does it look much nicer than the plastic diffuser that came with my CO2 kit, but ALL the bubbles are the very small ones that can be absorbed by the water in the tank. The stock diffuser that came with my 88g kit released a lot of larger bubbles that just represent a loss of CO2. For just that reason alone, I don't think it will take long for it to pay for itself. Looks Great! Works Great! Thanks Rhinox!

This diffuser is amazing. The majority of the bubbles are very very small. My aquarium is 30 inches wide and with the diffuser set up on one side I am finding CO2 bubbles all the way on the other side. So far this is the most efficient method of dissolving CO2 in my heavily planted aquarium that I have tried. My plants seem to be doing even better now that I have this diffuser.

So far, so good. Had no issues installing it. Only worked for 2 hours, and the valve on the co2 generator was bad. I'll update of there's any future issue.Month later, I've heard from others about clogging... I'm wondering if it's clogging or of they've running out of CO2? It took a couple of weeks to get the flow adjusted correctly. Just a thought.

I'm happy with this diffuser and it looks great in the tank. You need to be carefull when sticking it to the inside of your tank. I broke the stem on the first one I bought trying to place it. Stick the suction cup on first, then slide the glass in.

Looks like there are mixed reviews on this product and I think that could be because all of the diffusers are not the same. For example, the pictures show like 3 diff. Kinds of diffusers. The one I recieved was flat on top had a defective hole in the lower part of the spiral thing and produce fine bubbles from a single spot at very low pressure. I guess it all depends the seller

I took a chance on this one because I had an older model that didn't work very well, but this one works beautifully with my DIY CO2! Very tiny bubbles and my awuarium6 plants are very happy. I will be ordering a second one for my other tank.
