CO2 Generator Kit

So far ao good been two weeks now after getting the system, easy startup and tuning. I have this on a kasa smart outlet set to a timer and has run with zero issues. Would recommend using glycerin in the bubble counter vs water. Two reasons for this, you dont have to top the glycerin off as it does not evaporate, and two its easier to count your bubbles and fine tune it, added bonus it looks cool. Set up is straight forward, mixing easy just layer material and pre cool a 2 liter jug of water the night before and add some ice 1 hour before adding and keep it in the fridge. 2 weeks at 1.75-2 bubbles per second on a 20 gallon planted tank seems to be the sweet spot considering my plant load everything grows at a marked accelerated rate. All components are solid, tank is of good quality and safety vave ( blow out ) is a nice feature. Good set up that won't break the bank to up your game to a "high tech" tank. Very happy with this system.

Item work well with quality parts. Takes time and takes fine tuning to aquarium needs plants, fish, etc.. I placed it before and after picture after fine-tuning and have had great results. Customer service is exceptional.

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.

I only recently sent for another one of these after owning one for a few years. I'm now sending it back, but not because there's anything wrong with it! I never opened it before realizing I simply didn't need another one right now. However, I will say these are *great* little DIY systems, & I'd recommend them to anyone wanting co2 for their aquariums without buying the "usual" tank & regulator, plus needing to take it to be refilled with co2 when it runs out. Even if you do have such a system, this clsea set-up would be great to have as a back up for when you run out of co2. Mine starts building pressure *immediately* & is ready to use (in my experience) within 12 hours or less. Below is what showed up as a review I never completed from - ? - at least 2 yrs ago. It popped up when I was going to review the 2nd one just bought, so I'm not sure if I'm allowed to go back that far when reviewing. I'd completely forgotten that I'd begun a review so long ago: 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, as it's also typical of products made outside the U.S.A. It seems like they could at least get English-as-1st-language interpreters to edit their lame instructions. The ad descriptions, manual & 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 (pop bottle) 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. Recent update: I've learned that staggering the dry ingredients (1/3 citric acid, 1/3 baking soda, repeat) seems to keep it from bubbling out too soon. Also, I put ice cubes in the water & keep it in the fridge until ready to add it. Have to make sure you have 600 ml. after removing the ice cubes. Otherwise, following the directions that are right on the bottle's top works well. It is definitely a good idea to tilt the bottle about 45 degrees to pour in the water, & to do it quickly enough to prevent the reaction from bubbling out before you have time to get the regulator lid on. And do be ready to put it on immediately. The tank I bought a few years ago still looks and works like new. A warning: Don't try to clean the solenoid as recommended in their manual!!! If the instructions don't also tell you how to reassemble it, take that as a red flag/bad omen. I thought I'd try it once, & it took a long time for me to figure out how to get those tiny clips back on. I ended up using a little magnet to hold them in place & then push them down with a blade, but even then it was difficult to do. I used a small rubber band to hold the pieces together. Thing is, the solenoid didn't need cleaning at all once I got into it! I'd rather pay for a new solenoid than go to all that trouble again!

C’est le deuxième j’ai acheté, excellent système co2. Je recommandé.

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 ! UPDATE: la carga duro 5 meses !, 7 horas diarias, 1 burbuja cada dos segundos, la recarga fue muy fácil. OJO, se cristaliza parte de la mezcla de reacción al finalizar la carga, para remover estos cristales hay que usar agua caliente y un poquito de bicarbonato de sodio, esto los “romperá” y será muy fácil sacarlos.

Muy bueno, en m8 acuario trabaja excelente

I purchased this CO2 generator kit for a planted 10 gallon freshwater aquarium. It is my first experience with CO2 injection and I'm very happy about my purchase. The ingredients are easy to find, and relatively cheap compared to disposable CO2 cartridges or a full size CO2 bottle setup. The regulator is basic, but works well. Il like the fact that the selenoid and bubble counter are just one part. Feels less wobbly than having two seperate parts. The only con was the needle valve. It is very sensitive and can sometines be difficult to adjust exactly. I recommend this kit, specially for smaller tanks 20G or less.

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.
