180g tank, lightly stocked, plenty of filtration, and 5x 4" Discus coming tomorrow 

The guy is keeping them in 7.0 tap
I checked water parameters yesterday, and i am at 0 ammonia, 0 nitrite, <5 nitrate, and pH 7.8
I did a WC last night to remove my nitrates (and will be adding another established filter or two tonight/tomorrow)
Do you think I should try to buffer my Ph down between now and tomorrow?
The water in the tank now is just my tap, and dechlor, so I guess it must run in the 7.6-7.8 range regularly.
They say the worst thing for discus is changes in pH, so i'd like to adjust it before they get here if I need to adjust it at all.
I plan on acclimating them very slowly, so it wont be a sudden change in pH
And lastly if I do buffer it down, whats the best way to do it? Obviously I will have to be doing it on a regular basis from now on (if I go that route)
