What alkalinity booster is best

I've been trying to bring my alkalinity levels up using Seachem's Reef Builder but it's been slow going. What product do you use?

If you go to Frank's it's the same product

Thanks for the helpful suggestions. I fondly remember the good ole days when I just put a teaspoon of Mrs. Beal's Pickling Solution in each gallon of top-off water I added.
