I did cure the concrete pieces in freshwater for about 6 weeks before assembling the wall. The concrete that was used to put the wall together however was curing in the tank. And I agree, I had to offset a rise in ph with vinegar for a couple of weeks.
I currently have about 300 lbs of concrete curing to be used for additional structures.
As of this writing the tank finished cycling about 3 weeks ago, ph is stable at 8.4 and I have fish in it. I dropped in about 2lbs of real live rock and I am just waiting now for purple spots to pop up

I am just slow in catching up with the build timeline and getting pictures uploaded
