Questions about Safe-T-Sorb

I'm thinking about using Safe-T-Sorb as an economical alternative to eco-complete. I found two brands that have a very similar product. There's Moltan and Oil Dri. Which one is preferable?

Moltan: http://www.grainger.com/Grainger/MOL...KH8?Pid=search

Oil Dri: http://www.grainger.com/Grainger/OIL...ner-Size-4UB34

For the Moltan brand absorbent, there is one variety made with Clay Montmorillonite, and another one made with Diatomaceous Earth. Which one is preferable?

Also, is it okay to use the absorbent as the sole substrate in a low-medium light aquarium with regular liquid dosing and root tabs? Or should I also add a layer of soil at the bottom?

Edit: Is this the one I want? http://www.grainger.com/Grainger/MOL...KH9?Pid=search

Thanks.

The third one - 7941 is the item you want.

If you can't get it there, Drillspot will drop ship it for around $10 total.

Yes the 3rd one - Green bag is the one I used.

It is the only substrate in my 75 gal low-medium light tank. I use some root tabs and dose modified EI ferts. I don't dose NO3 as my tank doesn't need it. And dose lower levels of the others since my tank is lowish light and water changes every 2 weeks.

Hi blueshark,

Safe-T-Sorb #7941 is made from Monmorillonite clay. Oil-Dry is also Monmorillonite clay but more of a beige color. Diatomaceous earth is basically a powder and is not suitable as a substrate. I purchased mine from WW Grainger but was not aware of Drillspot at the time.
