I am looking for a CO2 system for my 55 gallon tank and just wanted what everyone recommeds ,

I found this

just wondering some thoughts on this? or if you recommed anything else

I am using a system like that but by a different brand that has a black color canister. I tseems to work very well in my 30 gallon aquarium even though its says its meant for 20gal max.

I think your aquairum can do really well with two of those turned on at once. Its still cheaper than buying a real co2 injection system.
