The reason I'm concerned about raising the pH is because without buffering capacity, your tank's pH will drop over time due to the good ol' Nitrogen cycle. I'm not sure how long it would take and if it would have a drastic effect on your fish, but wouldn't you rather keep the pH where it is rather than spend money on pH raising products?
BTW, my fingers are crossed...good luck!!!
