alkalinity ?????

[CKreef]

how do you raise your alkalinity with baking soda? Please help

Mix it with RO/DI water and add to the tank. Assuming it's the 58 I would try a teaspoon with one cup of water and test an hour or two later to see what it did. Go up as needed but be carefull not to raise it too much all at once.

I thought you had to bake it.

Baking it is good if you want to raise your pH as well. If your pH is OK, baking isn't necessary. Here's a good link which tells you how much to dose for a given volume and desired alkalinity increase
