CN1Pet Aquarium Planted Tank DIY CO2 System Kit D-201 Generator.

I received it in 10 days. It is a good product. This is used with citrix and baking soda but I convert it to use with sugar and yeast by cutting out the tubes that go into the bottles. I keep everything left especially the pressure gauge meter. The price is $23 is a little high plus delivery. This is shipped all the way from China. They do good bisiness. I give it 5 stars. Been using 2 weeks so far and nothing bad.

Gas leak between the cap and the bottle

I think this package should have one more bottle cap since most FYI systems have two yeast bottles and this system works extremely well, it's just weird you have to spend 9 bucks for a third cap

great kit for a small tank
