i've been putting baking soda in my tank for kh, cause my snails are sucking it down i went from 7kh down to 1kh in about a month so what can i use besides baking soda that will buffer the kh so that i don't have to keep putting the baking soda in?

Crushed coral should do it.
Can be added to the substrate or into the filter.

i will look for the crushed coral, but is there anything else i can get "over the counter" that will help with this??

I've heard of people buying crushed oyster grit at feed stores to buffer the water for snails. It's supposed to be really cheap, but I don't have experience with it.

Aragonite sand is also wonderful, and will usually buffer the pH to 8.0 or more. Obviously, a substrate option only unless you have a good media bag.

Crushed coral was mentioned already. That's what I use. If it's used as the substrate, it will last 3 months or more. After which it will have to be refreshed or replaced. As a filter media, it needs to be replaced every month. I've noticed my pH will drop very quickly after that. But, I do have very soft water.

i found some crushed coral at the lfs today, so i'm using that for now. i guess i'll have to actually use my test kits more often to keep track of things
