first reef, is tapwater safe in a starter nano?

what's the kH in your guys' tanks? Mine's at 200ppm, don't know if that's high or not. Increased pH = decreased margin for error. The tank's pH is at 8.3, and I guess I'll find out in a couple days if it'll go up

200 ppm is an unfamiliar measurement for me (as most of us). Does your test have a variety of measurement options? We usually use Meq/L, which might equivilate to ppm some how. But the best used measurement is D/Kh, (degrees of Carbonate hardness) which most people range from 8-12 D/Kh I think.

8.3 is fine for PH, I doubt it will go up if your tank is still cycling, watch for a drop once the No3 peaks. Normal ranges are 7.9-8.3.
