A Co2 regulator is what you’ll need to dissolve calcearous media in marine systems and it’s the best system to provide Co2 in freshwater systems. According to Aquariumplants.com, this model (made by Aquariumplants.com) is the best regulator after their Electronic Co2 Regulator (also made by Aquariumplants.com).
I was looking for a new regulator so I decided to give it a try. It’s a really good regulator but I am still not sure if it’s better than my Milwaukee regulator.
The price is insane! It’s twice the price of any other regulator.
Used with a Aluminum CO2 Cylinder, you can expect your CO2 supply to be stable and to last up to around 6 months
