Absolute best co2 reactor
This reactor has been a blessing to me. I tried other reactors and inline diffusers and nothing really worked well for my big tank(180g). This reactor is well built and is large enough to handle my 180g with ease. It worked so well I got another unit after running this one for a month. I now have 2 reactors, one on my 180 and one on my 60-P. I will never use anything else in the future. It comes with a check valve and easy to follow diagram. Its by far the largest co2 reactor I have ever seen and used. Most all other reactors are quite small, this GLA co2 reactor is all business. This has to be the best aquarium co2 reactor on the market.
