FZone Impareggiabili, il cliente al primo posto
Devo dire che all' inizio ero un po scettico sulla scelta di questo KIT fai da te, mi sono dovuto ricredere molto in fretta. Per cominciare il prezzo, rispetto ai classici impianti di CO2 costa molto meno, ti togli il problema delle bombole usa e getta che hanno un costo non indifferente senza contare che poi hai il problema dello smaltimento e per ultimo con una ricarica da 3€ ci faccio 3 mesi almeno. Intanto l' assemblaggio e la messa in opera una cosa facilissima, fai tutto in una mezzoretta ed è pronto all' uso, materiali veramente ottimi di prim'ordine, è 2 mesi che è in funzione e ho ancora più di mezza bombola disponibile. Però un problemino si è verificato, la valvola a spillo non si riusciva a calibrare, saltava da 15 a 30 bolle al minuto e non riuscivo veramente a calibrarla sulle 20 al minuto come io volevo, ho un acquarietto piccolo da 25 Litri. Decido di contattare direttamente FZone Europa lasciando fuori Amazon ma dialogando direttamente con loro. Impressionato dalla efficienza e attenzione ricevuta, mai successo di avere da una azienda una assistenza così attenta e personale, intanto le 3-4 mail scambiate ho interloquito sempre con la stessa persona ( Cheryl che ringrazio ancora per le attenzioni avute per il mio problema ) poi il tutto in lingua Italiana corrente ( senza traduttore Google ) invio un piccolo video per evidenziare il problema della valvola a spillo. Risultato? dopo 3 giorni avevo a casa non la valvola a spillo ma tutto il blocco del riduttore di pressione. Allibito e senza parole, non ci credevo, ora funziona tutto alla perfezione con le mie 20 bolle al minuto. Grazie FZone, il prossimo acquario che metterò su come cliente non mi perderete di sicuro. Io lo consiglio vivamente questo Kit per chi naturalmente non ha acquari esagerati. Prezzo conveniente, assistenza superlativa, costi di gestione molto contenuti senza sprechi.

This kit has been an excellent addition to my aquarium setup. The setup process was easy, and the build quality is solid and durable. The regulator works smoothly, offering precise control over CO₂ output. The system maintains stable pressure consistently, which has helped improve overall aquatic plant growth. Overall, this is a great value for beginners looking for an efficient CO₂ system.

Long term review
I’ve been using this DIY CO₂ cylinder on my 50 gallon tank for about a year now, and it’s been consistently reliable. Setup was straightforward, and even if you’re new to planted tanks, it doesn’t feel overwhelming. The design is simple and intuitive, which makes day to day use pretty hassle free. One of the biggest advantages is how easy it is to refill. You don’t need any complicated tools or special skills, just a quick recharge and you’re good to go again. That makes it much more convenient compared to some pressurized systems. In terms of performance, it does exactly what you need. CO₂ output is steady enough to support healthy plant growth, and I haven’t faced any major issues over long term use. For beginners especially, this is a great starting point before moving on to more advanced setups. Overall, it’s a practical, easy to use solution that delivers solid results without overcomplicating things.

Sistema genial de CO2
Llevaba varios años usando el sistema de dos botellas de plástico y la verdad, si llego a conocer esto antes, antes lo uso. Es una maravilla se recarga fácilmente y sin perder tanto tiempo como con las botellas (mezclar independientemente ingrediente, apretar, agitar hasta que coja presión, etc....en fin una tortura). Con este sistema echas los tres ingredientes, bicarbonato, ácido cítrico y agua y a correr. En un cuarto de hora o menos ha cogido la presión suficiente. Una maravilla y sin el peligro de que te explote una botella (que ya me ha pasado). Estoy encantado, espero que me dure años.

FZone 2.5L CO2 Generator
After carrying out a lot of research I decided this system would be the best bang for bucks system for my 120L system. I've been running the generator for 3 months now and I'm really impressed with it. It was easy to set up and the raw ingredients are cheap and easily purchased from Amazon. The powders are added and then the water is added very slowly with the bottle at a 45 degree angle. pouring it slowly slows down the chemical reaction and stops you wasting gas as you screw the regulator on to the bottle. I was getting 2 weeks of CO2 from one charge and when I added a CO2 reactor that figure went up to almost 4 weeks. 4 weeks of CO2 from 200g of acetic and 260g of Bi Carbonate is in my opinion amazing. The regulator is easy to adjust and the solenoid valve works as it should. The kit itself contains everything you need, except the raw materials and a drop checker. These can be picked up cheaply from Amazon. CO2 has made a big difference to my plants and algae growth is virtually zero now. This kit has been the best piece of kit I have bought for my aquarium in a long time. If you want to add CO2 to your system this is a great straight out of the box solution.
