I think you will find many of the people on this forum will use a baking soda mixture to raise Alk. Here is a link to the article that describe proportions:

and to a calculator to help you know how much to add to raise it to your desired level:

You might need to dose daily to keep levels up - I do it with a doser every 4 hours.

I totally agree with Shawn. When I had a similar problem, I used the 2 links mentioned above and my tank has been pretty balanced since...except at times when I slacked off....lol.
