C02 expansion manifold

So these are really solid. They come with all the hardware you need to install it. The instructions are very clear. It's really easy to setup. The whole c02 lineup is really easy and seems to work really well so far. I've had one issue, but support walked me through the issue (thanks again Candi).
I will say that the bubble counter isn't the most solid component. The metal feels more like plastic, and it kinda digs into the air line. That being said, it doesn't cut the airline and it does its job perfectly fine.

My overall opinion: i dont think you could find anything of similar quality in this price range. The corners cut to make it this cheap make sense, and aren't glaring issues like you would find on other models. I will be buying more of these in the future.

Love It

I have a 125 planted tank with fish. I have been trying to figure out how to get better dipersal of my CO2. The CO2 Regulator was the answer. I am very happy with it.
