    perfect and functional kit. Aesthetically beautiful and tidy. The regulation of the CO2 is perhaps too sensitive: a degree of rotation is enough to increase the supply a lot.

    The generator is very easy to setup, only negative is manual is 1xA4 in chinese ONLY. But with a littje help from aquarium fora it is not so hard to find the information needed to set it up. With the ingredients it took me 3 minutes to get it working and with a (bought separate) diffuser i can get a nice bubblecount of CO2 in my tank. No data about how long 1 mix will last, but the low cost of the ingredients (bought locally) helps to run it cheap.

    Clean and effective system for CO2 production. With the amounts of reagents indicated, 2 bubbles/second and closing the valve at night, lasts about two weeks. Sistema limpio y eficaz para la produccion de CO2. Con las cantidades de reactivos indicadas en el anuncio, a 2 burbujas/segundo y cerrando la valvula por la noche, dura casi dos semanas.

    Produit de bonne qualité. Emballage impeccable. Très simple à mettre en oeuvre, à faire fonctionner et le dosage du CO2 s'ajuste finement. Il est conseillé de monter un clapet anti-retour et un compte bulles. Entretien facile, ne provoque aucune salissure.

    I decided against a pressurised system because I didn't have experience. I was told that DIY CO2 was difficult to control but this product proves that theory wrong - the D501 delivers a consistent supply of CO2 and looks very sleek. I'm well impressed by the quality of the product and the speed of delivery.

    Very excellent product for first time user of CO2 in aquarium, this is available in very cheap rate compare to India. Product is very easy to install and effective. One thing which I have noticed, use tape (which is used by plumbers for tightening the tab) on mouth of bottle for not loosing the pressure and long lasting the material.

    Arrivato nei tempi previsti e ben imballato per la spedizione. Al suo interno c'erano tutti i pezzi come descritto. Peccato che appena aperto ho notato che il manometro della pressione non era den tarato segnava già 2 bar di pressione in aria ambiente (vedi foto) ed il manometro è una delle caratterisriche più importanti per il quale ho acquistato questo kit. Montato il tutto il rubinetto a spillo non è molto preciso ma con un po di pazienza e regolazione chirurgica il tutto funziona bene.
