Dumb Question

So I was looking at fish on Live Aquaria's site and some of the ones I am interested in require a KH of 10-15 and a pH of 6.5-7.5. Now my "dumb question" is that if I have my KH at 10-15 how am I supposed to keep the pH close to neutral. I always thought that by using buffers to raise the KH it would in turn raise the pH as well.

Raising KH will raise PH, yeah. I don't know about the site but it doesn't really matter anyways because most fish can be kept in any water (within reason) as long as you acclimate them well. Stability is infinitely more important than exact PH/KH/GH.

Thanks for responding, I was just wondering why they would list it like that if it is not possible. The site is owned by Dr. Foster's and is pretty reputable. I just figured I would ask to see if I was missing something. I know you need at least 3 KH (API test) to have a stable pH without swings. I am at a loss, lol. I would understand if it was GH but I have no idea what they mean and was just curious if anyone else knew.

I don't think that's quite true about the KH for stable pH, my pH is stable and my KH is only 2dH. I've seen others say they have stable pH with just 1dKH. I'm also not sure that it's impossible necessarily... My KH is low, as I said, but my pH is 7.6, so it's not an exact correlation. I think you can also raise KH to a certain point without raising pH. It looks like potassium carbonate can also be added to raise KH without raising pH...
