transition to higher ph

[XB aro]

my discus r at 6.6 ph, in a 175g, i want them to get use to my tap water at 7.3 ph, how many gallons should i change every day for them to get use?

I'd do around 20 to 25%.

i just tested my ph, its like 7.7-7.8, and isn't 20-25% alot?

If your concerned you can do increments of 10% each or every other day.

Do a 10% WC and see how much of an effect it has on the tanks pH. I would just do enough daily to move the pH a couple of tenths at most.

20% at a time is not going to change the PH enough to harm your fish. I've done it myself. If you want, do a test first. Drain some water out of your tank into a bucket, test the PH. Add a percentage of tap water and test again. You always want the PH change to be under a full point at a time. Less than that is better.

Is going from a 6.6 to 7.3 going to bother them anyway? Moving from an acidic ph to a more basic ph is the direction you want to go if you have to, right? A ph crash from high to low can be deadly.
I don't think it's much of a problem and should tolerated fairly easily.
