lowering ph with co2 and QT tank

[Wildiana]

ok, if my ph from the tap is 7.8 then my ph in my planted tank reads 7.2 somtimes 6.8 do to co2.

now my question is. if my QT suppost to be the same water as my tank so the fish won't stress much, should i be using tank water in my qt?

would the fish feel or go through any heavy changes going from high ph to nutrual ph?

Got to assume you are injecting with DIY to be getting a .4 swing, yes? There are ways to normalize your flow that would make your pH more uniform.

Yes, it is a good idea to have the water values as close as possible between the QT tank and the others to reduce stress. This becomes more important when the reason for using the QT is for sick or injured fish. They especially don't need the extra stress resulting from temp. or pH swings.
Healthy fish can handle mild changes in pH. Newly purchased or sick fish are, in many cases stressed. IMO, it's a good idea to shock them as little as possible.

For my fish, a change of no more than .2 - .4 is tolerable in my point of view. Just my opinion.

If the lower pH is due only to the CO2, it is not a big deal. That means if the KH/GH/TDS are the same in both tanks, don't sweat it. If the pH supppression is from other causes - buffers or other supplemets, it is a big deal and they should match as closely as practical.

yes its only co2 that is lowering my ph.

i'm currently looking into a pressurize tank to have a steady ph.

thanks guys.
