CO2 Generator System Carbon Dioxide Reactor Kit with Diffuser for Plants Aquarium (Without Solenoid)

It did take me a while to figure out how to set this up because my instructions did not show all the pieces that came with the unit.Once I figured that out, it charged up overnight and is operating fine. Don't know of results yet but it is a quality setup!

I've been using it for about 3 weeks now on my 10 gallon tank, at 1 bubble per second.Pressure at the beginning was 20BAR and it's still at 12BAR after 3 weeks which is way better than what I expected.I originally used yeast as my CO2 generator, but it required often changes which was very annoying - so I have decided to get this product after seeing lots of reviews and similar products online.The item was well packed, delivered to Israel fairly quickly, and the price is very affordable for a complete CO2 system. I am generally very happy with this product so far.My only complaint is the CO2 diffuser - even after using the method suggested of tightening the cap, it was still leaking bubbles for the sides so I had to get a different one. Works well with the other one.

Very durable and easy to use! Only downside is that it doesn’t last long and you have to replace the mixture inside every week or so depending on you preference on pressure release. Overall would recommend if you don’t want to go out and buy a big CO2 tank at the store!

It's not easy to pour water on the reactants and get the top screwed on before a lot of co2 escapes. That being said, short of burning natural gas or propane to generate co2 there's no better alternative product that I can find.

The good: Great materials, holds pressure well, regulator is consistent (once you set the bubble count you want, it sticks), comparatively inexpensive solution. I purchased this as my first CO2 solution. I'm a long-time aquarist, but have only just begun aquascaping. As I'm just starting out, I was hesitant to drop hundreds of dollars on a CO2 injector but I really wanted a healthy carpet of plants and everything I've read seems to insist CO2 is required for this. This seemed like a good way to get started without breaking the bank and I'm glad I made the purchase.The not-so-good: The instructions are terrible with the usual poor Chinese-to-English translation problems. There's even a part included that isn't referenced anywhere in the instructions and I haven't found it referenced in any videos I've watched. It's a small cylinder with a label stating "Preventing Crystallization Drying Filter Core." No idea what it does or where it goes or when to use it. I also had the same problem others have described where the diffuser doesn't diffuse. Large bubbles escape around the edges. A few google searches turned me on to the included black rubber-band which allows you to tighten the diffuser and that has resolved the issue for me. Others have had to seal the seam with silicon or plumber's tape. The poorly written instructions are the main reason I'm not giving this item 5 stars. It's a pet peeve of mine that companies defer to others (google/youtube communities) to explain their products rather than investing the time to produce clear, well-translated instructions included with the product.All in all, I recommend this product as a semi-DIY solution for those who don't want to invest too heavily in CO2 right off the bat. I intend to set up a couple nano tanks in the future and will definitely buy another one of these.

Ok I'm definitely impressed with this. I wish I had waited and gotten the one with the solenoid, but either way, this thing is a beast. The entire kit is great. The mixture is easy to mix, and this thing really holds the pressure. I'm going on the 4th day with the recipe they recommend, and the pressure is still above the green. At 2 BPS, it's holding the pressure great, and the diffuser is working flawlessly in my 55 gallon. Within 2 hours of turning on the C02, my drop checker turns green. Here's a tip for you, before you put your diffuser all the way in the tank, and get it positioned perfectly, make sure the ring that holds the disc is tight... LOL Don't ask me how I know that... I am setting up another planted 55 for my wife, and I will definitely buy another one of these. Some people say pressurized systems are better than the DIY ones, but that means nothing to me, this thing looks like a C02 tank, it's really easy on the eyes, and the bubble counter once dialed in retains it's settings. If you're wanting an All In One C02 system, for half the cost of a pressurized system, don't even think about it, just do it. This is everything you need to start injecting c02 into your tank, and it literally took me 15 minutes from unboxing, to running flawlessly in my tank.

The media could not be loaded. Great little device and very high quality I am very pleased with it. According to the manual, if I use 2 air bubbles/1s for eight hours/day this should last 20 days. Sweet!!

Tried to have it replaced but no response from seller
