My tap water is 8.0, consequently my tanks' pH are ~7.8-8.0. I now have R/O water avaliable...the pH of that is ~6.2. What do I do to bring down the pH of my tanks to 7, using the R/O water...do I age the R/O water...mix it? what should my mixing ratio be? How much of a pH drop is too much/fast? Is there a good pH stablizer that I should use once I get my water closer to 7.0?

/me digs up chemistry notes
what's the KH of both of the water samples?

is KH hardness?

It's the carbonate concentration =) aka alkalinity aka carbonate hardness aka carbonate level aka temporary hardness |

ok, crap that's about the only thing I don't have a test for LOL
When I first got my 29g tank and used the dip-strips, my water tested out hard-as-nails...but last Tuesday I got a water softener installed, so I have no clue what it is now. We use salt in the softener...and the R/O water is softened before it is R/O'd...so i'm sure the KH will be markedly different.
I'm planning a trip to Petsmart next Sunday...I'll pick up a KH test then. ah...the list gets longer... hehe

what about pH stabilizer? Do I need to do that chemically? Or should I be able to keep it pretty stable with a decent water mix?
How fast/slow should the pH drop? Just with one water change I had a 0.2 drop (from 7.8 to 7.6)...is that ok, or too fast?

When you get the KH for both samples tested I'll be able to determine:
1. ratio of water types to use to get an ending pH of 7.0
2. the KH of the resulting mixture
3. how many licks it takes to get to the center of a tootsie roll pop.

Good, you better. My equation page is getting lonely.

ok, i got some:
R/O water straight out of tap:
KH: 25
GH: 20
pH: 7.0-7.1
You want the KH and GH of the tank, and the softened water too?

I need the KH and pH of whatever water you intend to mix, so that's the tap water and R/O water?
