plain, cheap, unscented, clay Kitty litter provides next to nothing, but it has a high CEC. CEC is too hard former to explain in one post, but essentially its the ability to absorb excess nutrients and release them over time.
CEC is good, but a mixture of soil and crushed vermiculite is better. (4 parts sifted clay-rich soil, 1 part vermiculite, moistened, and kneaded together) has the same benefits. just cap with sand. there's another thread below this one that covers soil.

I've studied using soil in planted tanks quite a bit. I've been wanting to do a NPT but I don't want to risk crashing my parameters because I don't have a whole lotta plants.

I read/saw some people using kitty litter in their planted tanks and having great success with them. I'm not sure how the plants are benefiting from kitty litter tho O.O

^^ sucks up the excess then slowly releases it, the plants take what they need witout having a huge risk of algae if im not mistaken.
