RO Water in Planted Aquarium w/ CO2

[Hulka9]

How do you properly treat ro water for an aquarium that uses co2? I've bought Kent Marine R/O Right and plan on using that, but from what I can tell it doesnt correctly buffer the hardness. From what i've read, adding a buffer other than crushed coral or another natural method will throw off the results of the ph/kh chart to monitor co2. But that also poses a problem because it takes so long to adjust the kh. Can someone help me out?

Just use tap to balance it out to the hardness you want.

I believe Seachem Matrix is used to support purified water in freshwater. But as stated above, a lot easier just to use tap water since it comes with buffers "naturally".
