What should I be aiming for Alkalinity ?
Is 8 ok or should it be closer to 9? Remember for me to get it there I was dosing more DkH and that caused my pump problems
My tank is mainly SPS

What you should be aiming for Alkalinity is partly a personal choice. Many people like to run high alk levels like 9-11. So long as you know what you're donig and your levels are in balance (with Calcium) then that's fine.

If you want to play it safe, generally speaking most people target 8 as a comfortably manageable level. I keep mine at 8 because if it slacks and slips to 7 it's not the end of the world. If it slips up to 9, still not the end of the world. The danger of keeping alk lower or higher is that your margin for error decreases at either end.
