If you really have a heavy load, then yes. It’s rated for 130 gallons with a heavy load and higher with a light load. A heavy load is upwards of 1/2” of fish per display gallon. Even if you have less than that, the Co2 will work much better than the Alpha 200. You just might have to run it a little more on the wet side to keep it consistent.
