Is seachem alkaline and acidic buffer safe for axolotls?

[CBootheAxie]

Recently I switched my axolotl tank to rodi water Since my tap water was causing nitrite spikes. I have been adding seachem equalibrium to replace the minerals however my ph is dropping from 7.4 to 7. I was wandering if anyone had experience or knew if seachems alkaline and acid buffers were safe so that I could keep a stable ph of 7.5 which is what my axie is used to from the tap. My kh is at 3dkh and im also considering raising it but I am worried that it will raise my ph to high. Any advice on useing rodi water would be helpful.

I use no chemistry at all in my axolotl (and newts) aquariums. No problems (perhaps my tap water is favourable).

But I can say axolotls thrive well (and breed well) at pH 7 or slightly below.
Moreover, at pH 7,5, ammonia dominates ammonium and it's much more risky for the animals :
