Currently I have only the Special Grade Sand and Salt Water in the tank.

I am using Seachem Reef Salt.

PH: 8.0
Calcium: 420
Magnesium: 1000
Alk: 6? This one bothers me. I did 3 tests all the same. (API)

Is this normal? I used RO/DI water.

I agree with the others, you need to get the Mg to 1300-1350, calcium is a tad high, but no biggie there, it should be 400, so 420 is nothing to worry about. Also PH, should be 8.3

I would suggest like the others to get your Mg, to the proper range, and stable then work on the ALK, once you can get your ALK to your desired leve (7-12) this varies with many. I keep mine at 7 because I use the Zeo method, but many have theirs higher. But once you can stabalize things, I think your PH will be fine also @ 8.3

I can't say much about Seachem salt, as I never used it. But I never had issues with IO Reef Crystals or with Reefers Best (which I use now)
