IME i have never experienced a giant build up of gas pockets because my cories sifted through the sand and my cichlids digging also stirred it up. If ur not going to have a lot of movement in ur substrate just be cautious about them. I changed my gravel out all at the same time and put sand in leaving a little water which carried some bacteria in it. I let my fish sit in a QT tank while i let it do a mini cycle for about 30 hours.
I guess the thing I worry about is what if the mini-cycle went longer than 30 hours? I was reading on another forum how this person's mini-cycle went for almost 2 weeks. Not that my QT wouldn't be a safe place, but I'm sure my fish would be a little stressed.
