generally anywhere from 8-9 is ideal. I've heard of tanks run as low as 6 and as high as 11. Consistency is the most important especially if keeping SPS. If you're not keeping SPS or totally loaded up with LPS most likely you wont even need to test it as regular water changes should keep the level in check.

I'm sorry what are those parameters in PPM ?
