MagTool4L Aquarium CO2 Generator System Carbon Dioxide Reactor Kit with Regulator and Needle Valve (2.5L with Solenoid)

I bought one of those DIY CO2 systems with the caps you put overtop of two 2 litre bottles, and it did work well. But this system is definitely an upgrade! You don’t have to squeeze the bottle to start the reaction going, and that was sometimes a bit of a pain. With this system you just pour in all the ingredients and tighten the lid on. I saw videos saying to use ice cubes, but regular ice cubes don’t fit in. I just used cold distilled water instead and I could hear the reaction starting but I doubt I lost any significant amount of CO2. The 4L model has 3 times the capacity of my DIY unit and comes with a solinoid. I hooked up the solinoid to the timer my light was on, and that alone will make it last 3 times longer given my lights are on for 8 hours.I have been using it for 3 weeks now at 3 bubbles per second and it still has lots of pressure and my plants are growing really well. I highly recommend this unit!

I wanted co2 on my planted tank for quite a while so when I saw these I jumped on it. I bought the 4l version for a 36gal tank. Looking back I could have gotten the smaller one, but I would have to recharge more often. I think the little one would be maxed out on roughly a 50gal tank. The process is simple - add baking soda, add citric acid, and add ice. The ratio shown on the bottle will work but a 1.3 ratio for acid works better. Check out my photo where I wrote how much of each ingredient I used and it yielded me almost 500psi. Also use ice in place if water for more pressure. The first time I mixed it I put the dry ingredients in and then the water and WOW the amount of air (co2) that rushed out as I tried to put the cap in was unbelievable. That mix yielded about 400psi so the ice gives me 100psi more usable CO2. I am running about 1bubble per sec and the unit is on about 12 hours a day and the first tank lasted about 3 months. With the higher pressure I hope to get an extra month out of it. Overall quality is nice. Super easy to clean and very easy to use. The ingredients for it are also relatively cheap. I bought 5lbs Millard citric acid for $25 (the bigger bag is cheaper per unit) and this should last me about 3 recharges or roughly a year. Baking soda is cheap and sold at Walmart or Lowe's in the pool section cheap. Both chemicles are safe enough to eat so no worries about dangers (citric acid is the sour taste in sour patch gummies and other candies and baking soda is in toothpaste and some baked products). Overall a cool system at a good price and a fun little experiment to do with kids.

El producto tuvo una falla, la válvula solenoide falló, sin embargo, el proveedor respondió de la mejor manera, comprendo que esto puede pasar, lo que verdaderamente cuenta es el tener la respuesta oportuna del vendedor, ya está funcionando Perfecto, la carga de CO2 lleva casi un mes y no ha bajado ni la mitad de la presión en una urna de 150 litros, si, lo recomiendo.Sin embargo mi queja no es con el vendedor sino con Amazon, este es el segundo feed back que mando ya que no les parece nada, aún así sea una opinión positiva del proveedor, me siento realmente tentado por este y otros detalles a cancelar mi cuenta y comprar por otras plataformas, llevan sus políticas a un nivel de exageración extremo.

The CO2 regulator came all bent and once I set it to the flow I want it seems to stop after 30 mins

C’est bon produit, très satisfait, je recommandé
