Calcium & Alk. Additives - What's best?

[MikeP]

I used a liquid additive called DKH plus for a while (can't remember the brand name, I bought it at Elite though). On a small tank like yours a bottle would last quite a while and as I recall it wasn't too expensive. Now I'm using baked baking soda but my tank is pretty big and also uses up a lot of alk, I'm dosing daily. The baking soda method is working out really good for me.
