Not worth the money. Had it running about 3-4 bps, and it ran out in less than 5 days. Having to try to clean out the rock hard chunks in the tank and refill it that often is a huge pain. I had it for about 3 weeks before switching to a real co2 tank from Airgas and a UNS dual stage regulator. Wish I had saved the more than $100 I spent on this plus supplies and used it towards the real setup I ended up having to get anyways. I have a 60 gallon breeder, so can't speak for how long it would last for a nano tank. But even then, the annoyance of refilling it would still have me using a real setup even for a small aquarium.

Definitely worth a try. I will update this review after the first few months. So far, the pressure was slightly under half but my tank is small so I wasn’t bothered. Diffuser is good, regulator works, solenoid is adequate for the price. I won’t put it on a timer. I just manually turn it on and off.Turn off at night.

Usaba antes un sistema de dos botellas, este es muchísimo más efectivo y fácil de instalar y mantener. Lucen componentes de buena calidad, habrá que esperar para determinar su durabilidad, a un mes de uso todo muy bien. El sistema requiere menos piezas para su puesta en marcha, lo cual creo que será más confiable para evitar fugas o ajustes. Fue fácil de poner en marcha, hay que tener la paciencia de esperar unas 18 horas para alcanzar la presión de operación y LEER las instrucciones. El conteo de burbujas fue suficientemente preciso. El paso crítico es: una vez colocados el ácido y el bicarbonato, hay que verter agua FRÍA en un ángulo de 45 grados y tener la tapa y lista, todo esto con el fin de tapar la botella lo más rápido posible ANTES de que la reacción química comience con toda su fuerza y así no desperdiciar nada del CO2 emitido y evitar salpicaduras en las roscas que pudieran cristalizarse y dificultar su posterior abertura al parecer la duración de la reacción con 7 horas diarias a razón de 1 burbuja cada dos segundos será de al menos un par de meses más, esto habrá que comprobarlo, pero la presión después de casi un mes no ha disminuido en lo absoluto. Altamente recomendable, no le hace falta nada para instalarlo y además luce muy bien !

Works very good and easy!.Update after 1 month: this product is really good and esasy to use, i use it at 2 bubbles per second, and it run for the whole month, even a little more on my 30 gallon tank. (Model G700s)When i refill it there was like cristals in the bottle but i think is a normal reaction, i just empty all the bottle and refill it.I never seen my plants grow so well, i recommend this product 100%.

I searched for weeks to find a setup that would work for my tank. I decided to go with this one because of the other reviews and the fact that customers who had issues, reported that their customer service was very helpful. I have been running this tank for three weeks and have had no issues. It's nice to know that if something does go wrong, customer service will be helpful. I used the diffuser it came with at first, but I personally didn't like the look so I switched to an inline diffuser and still works great. I didn't order the ingredients from them, I just went to the grocery store and picked up the baking soda and citric acid in bulk.A few tips regarding the set up:- do yourself a favor and order a scale to measure the ingredients. You want to be very accurate here.- make sure your ingredients are not clumpy. This isn't really an issue with citric acid but the baking soda will clump up. After you measure it, take a few seconds to sift or break up any clumps by hand. This will ensure that your reaction is strong and lasts.- the first time I added the ingredients, I didn't sift the clumps and I used coldish water. I also added the ingredients in the order they say. That tank only reached ~18 kg/cm on the gauge and the reaction lasted about 5 days. However, I found that layering the ingredients, getting rid of the clumps and using really cold water yielded way better results.- you want to use ice cold water! This is very important to make sure the reaction occurs to its max potential. I place a jug of water in the freezer to make sure it's very cold (but not frozen).- order yourself a drop checker so you can be sure your co2 levels are safe. It will help you dial in your usage. You can't do this by eye, you'll need to measure it somehow.Doing the above got my gauge to 40kg/cm in about 6 hours and I've been running for almost three weeks. I do have it connected to a smart plug on a timer to make sure i keep co2 levels safe for my fish but enough for my plants to thrive. Your usage will be different of course but if you follow these tips you will maximize the reaction for your tank.

It took me a while to get around to setting this up. I'd done DIY co2 already with the big soda bottles & all that jazz. I was never a fan of the yeast/sugar mixtures, so had done them with baking soda/citric acid. One time a bottle blew up. Yikes! The main problem was that they just ran out too quickly & I'm too lazy to keep up with them, so I'd just gone low-tech for a long time. Then I bought some high-tech plants, & had only a single co2 tank, so thought I'd give this one a try.Once I finally got around to putting this one into action, at first I was irritated with the instructions & the bad grammar, etc. That's just typical of me, though. It seems like they could at least get English-as-1st-language interpreters to edit their lame instructions, though. The ad descriptions & videos are even amusingly lame, but they do show enough to get the gist.However, the quality of the stainless tank & attachments is really as advertised. Well-made! I docked a single star mainly due to the one thing that isn't made all that well IMO: the solenoid valve is flimsy, especially the way the wires are attached. I'm not crazy about the diffuser, either, but that's a minor issue.I've had this up & running now for more than 3 months in a smaller (25G) aquarium, & it's still putting out the co2 like a champ. I did replace the diffuser with a whittled chopstick end placed to pull into a wavemaker to blow the co2 around the aquarium better. It's great how long it's lasted, & the pressure in the tank is still pretty high. With the old DIY system, I think I had to change it out every few weeks or so. (Not to mention that exploding bottle experience. I'm still coming across crusted baking soda spots here & there.)All in all, it was a good buy & worth it.

Llego el equipo completo como dice anuncio. Preparé la mezcla como indica la instrucción en el cilindro. Esta funcionando conectado a un temporizador que compré aparte. Regulado a 1 burbuja x segundo. 2 semanas ahora conectado y se mantiene la presión. Solenoide trabaja bien. El resultado en las fotos. Así se inició, y ahora las plantas después de 2 semanas de uso. Muy bien crecimiento de las plantas. Muy contento con la compra.
