GH, KH and PH

[Boohoo]

I will be moving in the next couple weeks so yesterday I got a water sample to see how it compares to the water I have now. My water from my tap has a PH~6.2 GH~40 KH~20 I have been adding baking soda with every water change because of the low KH so what my tanks have for readings are
PH~7.2 GH~40 KH~60. Now the water where I am moving PH~7.2 GH~160 KH~140. Will the difference be stressful for my fish? What should I do to make the transition less stressful?

Someone must have some answers??? :idea2:

It wont be that stressful on your fish if you acclimatize them slowly, the KH is not that different in the new place you are going, the GH has a little bit of a difference but nothing to be concerned about. You could slowly raise the KH to about 100 a few weeks before you go if you were really worried. Did you test the ph on the water from where you are going straight out of the tap or leave it for a few days?

I tested straight from the tap, but now that you mention it, I will get another sample and let it sit out and retest.

If you drip acclimate the fish you should not have any issues, fish are very adjustable so long as the change is not too abrupt. The TDS of the two samples is going be quite large, and offers the potential of osmotic shock (what most folks call "pH shock" and which is not real, but osmotic shock is quite real). The KH is over 2x higher for the tank water to new source and ~7x for the two sources, the GH ~4x. Both of those are non-trivial differences.
