Either way is fine. Test the ph of the RO water and buffer if needed. It is important to not bring it down too quickly, also test the ph frequently in the display while you bring it down.

I would remove 3 gallons an hour till you get it where it needs to be. what is your sg now?

Do you have inverts or just fish? Inverts are sensitive to a decrease in SG. You would have to lower it no more than .04 per day. They like the SG to be at 1.025-1.026 What is your SG now? What are you using to measure SG?
