It is a clay product only fired in a kiln for so long. Eco-complete is an example of how it would feel if it were baked longer.

I've heard very mixed results with Oil Dry, as if some batches were kiln-fired to higher temperatures than others. And that you can test in advance by putting some in a cup of water, then repeatedly freezing and thawing it. If it falls apart or turns to mud, it's no good for an aquarium.

I'm thinkin its the oil dry too, don't know the make up process tho. I have a tank with sand over the same soil and it feels compacted, hard to push the plants into the soil but they stay when put into the sand / soil sub. The soil / oil dry some plants come back out no all tho, my hydrocotyal sometimes comes out I think the Cory cats do it tho. The only reason I can think why plants stay in that mix is because its so deep. I would like to change it but don't wanna desturb the growth of the plants.
