Juvies and pH

we're about to move 35 2mopnths old discus to a new tank. I just noticed that the tank they grew in is around 6.0 to 6.2 in pH... what pH variation would you recommend as the pH of the second tank is 7.2?

I added some Neutral regulator and Discus buffer to the new tank and first reading is about 6.4 now...is that too high for a first pH change for them fishes?

We have 9 Tetra emperor in the new fish tank I hope the drop is not to high too...


thx for the info!

Are they new to you or just moving them?

moving them for the first time
