Increasing KH?

[ares]

Since the arrival of the new light I've been working hard to get my water parameters back to normal and remedy my neglect. In the past week through PWC's I've managed to get my nitrates from somewhere around 160 down to 35. Everything else was perfect except for the nitrate lvls. I did a full water test today and have noticed that my KH has dropped from 8 to 6 in a week. Is there a natural way that I can get it back to where it needs to be?

Use Arm&Hammer baking soda to raise your alk. This Reef Chemistry calculator will tell you how much you need to add.

Is this safe to do if there are fish and snails in the tank? Should I add it to my filter or directly to the main tank? Thanks so much for your help.

It's very safe. Use the calculator I linked to above to determine how much to use. Then add that amount to some RO water and just dump it in your tank. It will cloud up, but it dissipates quickly.
