Rhinox Spio III CO2 Diffuser & Glass Reactor - Compatible with Pressurized CO2 Tanks - Latest Technology Guarantees Optimal Diffusion of CO2 - Improves Growth & Health of Aquatic Plants

I received two of these diffusers and they worked perfectly right out of the package. Nice fine bubbles - perfect. I have them installed on a pressurized system. Quality was very good and they are attractive and fit in very well in my planted tanks. The design with the spiral tube the bubbles travel to reach the ceramic diffuser adds to the overall attractiveness and functionality of this product. I will definitely purchase this item again.

Great quality product with a nice design. Good packaging and quick shipping service

Easy to use and install. Worked right out of the packaging. I read a review on here that said they were having an issue getting the bubble to go up the spiral. I'm not sure what they were doing but I used this right out of the packaging and it worked like a charm. It does say to tilt the diffuser and not put it upright.

Again this product arrived from vendor with no apparent original packaging. It was simply wrapped in bubble wrap with a printer label. It looks like what I ordered and was in perfect condition. So I will assume it is the Rhinox diffuser. It is working fine in my tank. Please be aware that this product was not designed for use with home made co2. If you have a home made system it must not have any leaks as it takes a considerable amount of pressure to make the diffuser work. You will not get bubbles like those in the picture. I get 2 to 3 streams of very fine bubbles. A simple way to test your system for leaks is to take an art or makeup brush and dip into very soapy water making sure it is sudsy on the brush. Brush library on your joints and bottle caps once your system is actively making co2. If it foams or bubbles you have a leak that needs fixing.

Very fragile! Accidentally broke the first one trying to connect it to the co2 hose. But it's working amazingly in my planted tank.

I bought this for a pressurized C02 injection set-up. The diffuser works well and as others have mentioned soak the end of the air tubing in some hot water to get a good connection with the diffuser. The product is fragile but what can you expect from glass? I think people that said it's too fragile used to much force. However, one thing I don't like about the product is the cheap suction cup that comes with it. The suction cup doesn't fasten tightly enough around the stem of the diffuser causing the diffuser to keep popping out of the suction cup.

This product was a delight. Less expensive than Fluval. Functions better than Fluval. Looks like a little glass flowerbud. Very very satisfied.

Just purchased two of these diffusers for my 55 gallon planted aquarium. Received them very quickly and am happy to say that I received exactly what I wanted. Not only do they perform extremely well (producing tiny little bubbles that are easily absorbed by the water before they reach the surface), but they look really cool too. I am currently using them with a homemade reactor (2 liter soda bottle, some airline tubing, silicon glue and a mixture of 1/2 tsp yeast, 2 cups of sugar and 1.5 liters of warm water) and it works great! I hope to buy a real CO2 system (running on CO2 canisters) when I have a little extra allowance, but now wondering why when my homemade solution works so well. BTW, these diffusers would work just great with a store-bought CO2 system as well. At any rate, I'm very happy with my high-quality product and it is Amazon Prime -- bonus!
