Rhinox 2000 - Glass Reactor for Aquarium Plants CO2 Diffuser Pollen Aquarium Ada Beetle

Very nice looking product. Functions pretty well for a glass diffuser, but not optimally. I run pressurized CO2 and have the pressure pretty high (~20psi) and about 2-3 bubbles per second, and the bubbles come out of the diffuser mostly around one edge and sometimes quite large. There is not uniform diffusion across the surface. Also the packaging of the product gave me a little scare when it was shipped with another item through Prime and the only thing separating them was the bubble wrap the diffuser was packed in. It was just thrown in the box with the other items just wrapped in bubble wrap.

I'm giving this diffuser 2 stars because I received and returned two of these. I should preface this review a bit by saying that I have bought and used several Rhinox products for my planted aquariums and these are the only two that I have been unsatisfied with. My nano reactor, bubble counters, drop checkers, check valves...all high quality and great, if not exceptional performance and value. These Rhinox 2000 reactors are high quality and a great value, but two times, they failed me. It may just be my bad luck, so decide for yourself.My issue was that these diffused my pressurized CO2 very poorly. Rather than the fine mist one should expect, these produced large, surface agitating bubbles, mainly around the edges of the reactor. I did clean these, as instructed on the packaging, even though these were experiencing issues from the very first moment. The cleaning did not solve the issue. The product also instructs you to work at a pressure of 30psi, with at least 5 bubbles/second. Both of those parameters were checked and verified, and in my case, 5+ bubbles/second would overdose my 20 long. Even so, 30 psi, 5+ bubbles/second provided no improved diffusion. I'm sorry to say, twice was enough. I am now back to my Rhinox nano in my 20 long, and it's doing just what I need.I also want to praise the seller, Marimo Pet Store. They sell quality products and provide excellent customer service. As far as a seller goes, they're top notch and will try to resolve any issue you have. They're great!

Great diffuser. Really fine bubbles, but it clogs in a few weeks and you have to soak it in bleach to unclog it.

Seems to work well. Generates a "tweeting" sound when CO2 flow is high.

Sucking cup doesn't really work

Tiny co2 bubbles is coming out in the diffuser that's good but bad thing it's only coming out in small part of the edge of the diffuser i already soak it in bleach but still same... hope marimo pet can help me and solve this

Same problem as TOO MANY on here have already stated.... these diffusers are crap. Youll get big bubbles out of one tiny spot on the diffuser. I bought two for my two 20 longs both have the EXACT same problem... come on Rhinox... this is crap. Are these even real Rhinox? I cant help but suspect these are imitation Rhinox with the quality a lot of people have been reporting.

Does a very good job forming small bubbles. Easy to clean with a soak in bleach.
