baking soda is chep and works great.. :-D i always have problems with alk so i use it to pick it up, might be because of my calcium been at 500-600 :lol:

Baking Soda will raise Alk, but not pH. To make a good buffer that will do both, use a 6:1 ratio of baking soda to washing soda (Arm & Hammer Super Baking soda). It is available in most HEB's on the aisle with the laundry detergent. Chemically it is sodium carbonate. This mixture is basically what you are buying when get any of the commercial aquarium solid buffers. Add some high priced water and you have the A part of a two part additive.

Do you just use them plain, no prep?

Stephen,

Check out this thread. I posted it yesterday to answer some questions on my 2 part system. It has a description of how I make up the buffer and apply it. Let me know if you have any questions.

Thanks! any way to save money is always a plus.

I can make up what would be a $30 bucket of Kent buffer for about $2.
