Re: [APD] pH control

I read that API pH down works by reducing KH. So what buffers water at a pH
of say 5?
My tap water is a pH of 6.6-6.8 and has a KH of 1 (if that) with zero GH.
Sodium bicarbonate, which I use to buffer my water, does it by producing HO
so it raises the pH. What buffers at a low pH?
