Dsb is a deep sand bed. Using a dsb will promote anerobic bacteria growth, which is the bacteria you need to change nitrates into nitrogen.... And ideal ph is 8.0-8.3, but a stable ph is more important than how high or low it is. If it holds steady at 7.6, I wouldn't touch it. When you start adding chems to change your ph, it usually will just de-stabilize it, causing it to swing drastically, and that's what kills fish.
