190MPH

As I posted previously, my fishless cycle is basically done. As it turns out, a visit to the LFS that I will be getting my stock from had him out of the torpedo barbs I want. He had the sterbai cories:19: and danios, but I don't want to stagger them too far apart for fear of a mini cycle. He will have the barbs early this week. That is fine because it will allow another week for the cycle to become more stable (what's 1 more at this point). My question is in regard to pH. I noticed it has dipped a little, down from 7.8-8 to ~7.4. I'm sure this is due to the KH dropping from 70ppm to 20ppm. Can I do a partial water change to maintain the KH and pH for the extra week of cycling, until I do the large one next week before adding my fish? My mind tells me yes, because this is what I will be doing weekly anyway, which should prevent any crashes. I hope I explained it OK
