All my tanks use it, and it's fine. There are a couple things to be aware of:
1. Put it through a screen or sieve and get out all the chunks.
2. I am successful with 1" of soil, and 1-1.5" of sand. Less cap= terrible mess later.
3. Don't move plants, and if anything spreads by underground runners put in plastic dividers to contain it. Less disturbance is better.
4. You will get bubbles. Don't worry about it. Just poke the soil with a skewer once a week, or when you see part of the sand mounting up.
