2L Aquarium CO2 Generator System Carbon Dioxide Reactor Kit with Regulator And Needle Valve For Aquatic Tank

Its great CO2 generator, easy to setup, there is instructions in english on the manual. I receive it with faulty solenoid, I contact the seller, the seller was so supportive and they compensate me a value of solenoid to buy myself since they dont have the solenoid in their shop. Amazing product and great support from seller. Thanks for amazon for bringing these products to their website.

Easy to handle and very good product. I am using for my 150L tank and seems good. The 2L looks very premium as that brand like Fluval. The price is very good compared to other sellers. You are getting everything required with this kit except the materials citric acid and baking soda that required to buy from Amazon itself. I recommend this seller and delivery was also very fast. Thank you.

I received the product and I am very happy with the quality of the product. Every component of the item is of good quality. Even there was a missing item in the package, the seller was very helpful to resolve the issue. Really recommends this seller.

I ask for return, but no response. very bad product. don't buy, waste of time and money. buy from local market, at least you get a response

It is a good product and works well Co2 last for a long time (4 months) Easy to use

Good product. Received the complete kit which included the solenoid,cylinder,diffuser, tubing & all other parts. Works as expected. Best choice for small tanks(anything that holds <80 ltrs of water).

Good quality product, but terrible instructions written in Chinese. I think I am missing some parts but unsure because it's written in Chinese.

For 2L Cylinder Make sure both valves are closed. Follow 200 Gram Ciric Acid- 1st Step 200 Gram Baking Soda- 2nd Step 300 Ml Water 3rd Step. Do not put water directly You should keep position of 45 degree angles then slowly put the water.... Once you done Immediately close the cylinder. when you see the needle starts to move up, you can connected to the aquarium, ratio of bubble I bubble in 3 seconds for 60cm length aquarium....and 6 hours Daily.... in this ratio it last 2-3 months minimum... Citric Acid and Baking Soda Both Better to Buy from Amazon itself, Citric Acid is not common to buy in supermarkets.. For me it's works perfectly.... and I'm happy.....
