Best CO2 Reactor???

[saugata]

Hi! All,

For a 90 g heavily planted tank which is the best CO2 reactor? Moreover, what would be the minimum flow rate of the power head to be used in conjunction with such a reactor?

Thanks in advance for your suggestions?

My office tank is more or less the same volume as yours and I am using an external reactor manufactured by AquaMedic called Reactor1000.
