65g to 120G Tank Transfer

[hihikeke]

I have everything ready to go!! :bounce2: One question I have is do you think that I should transfer all my "old" water from the 65G to the 120G? I have prepared about 80G of "new" water running aside for a month already, if I add all of my water from the 65G, do you know if I will it will affect the water quality because the 65G tank is about time for 20% WC.

why risk it? just make all new water, why bother use water that already needs to be changed. its not like you are going to be losing tons of bacteria throwing away the old water. if you want to save money and some time then i guess it wont really hurt to use it but i feel that using all new water would be best.

coz I think there might have some good bacteria from my old water. Time & the of water is nothing when comparing if there is any losts during the transfer.
