Cycle complete! But what to do with the pH?

[jess128]

I've had live rock in my tank for 4 weeks now and right now my water conditions are:

ammonia: 0
nitrate: 0
nitrite: 0
SG: 1.023
pH: 7.8

How can I get my pH up? I know using a "pH Up" solution is frowned upon, but is there anything else to do? Also, I'm going to start my tank off with a pair of percula clowns, when is it safe to add them? (I was hoping this weekend, but it will probably be next.)
