Co2 System For A 100Gal Tank

[SDWalters]

I am looking into adding CO2 to my planted tank as well as new T5 lighting... as well as increasing the plant mass!

Can someone recommend a good system to run for such a tank?

Thanks in advance

DIY i'd say. Cheapest for that size tank. You could split the diffuser into two at either end of the tank aswell to increase circulation. You'd need a big cannister. Probably 2kg would last long enough depending how much you add.
