Very Happy

Excellent build quality and easy to follow instructions. It takes all of 3 minutes to install. This co2 reactor is much larger than any other reactor I have ever seen or used. Perhaps thats why it works so well. The way the whirlpool motion happens inside the co2 reactor is quite cool. This is what gets the co2 100% saturated. I run a fairly high bubble rate on my 180g tank and this reactor has no issue handling this tank. I will be buying another one as soon as my tank arrives next week. Very happy!

Outstanding co2 reactor

I purchased this reactor to go with my Pro-DS co2 regulator. I really like this reactor because it keeps co2 stable in my 180g tank. My previous co2 reactor was simply to small to handle the co2 going into it. Simple installation and very cool whirlpool effect it creates inside. It also looks cool unlike the rest you will see on the interwebs:) Very high quality unit.
