What is the correct Alkalinity?

[ChrisK]

I was just wondering what the correct alk is for a reef tank. Mine is at 6.0, my calcium is around 440-450 and pH at 8.0. Should I make any adjustments?
Thanks

I like me Alk to be around 9-10 I think the generally accepted level is 8-11.

Correct, 8 to 11 dKH. Or 2.86 to 3.89 meq/l

HOW DO YOU RAISE THE ALK?

[melev]

You can purchase various products designed to raise Alkanity and pH. They work together quite often.

Of you can raise it with Baking Soda. Mix up a teaspoon in a cup of RO water, and then add it gradually to the tank in an area of high flow. Wait a few minutes, then test the water to see what the level is. Add more until you've reached 8 dKH.
