Sand Troubles

[lowee]

I've got a bit of a dilema with the sand in my new set-up, its black tahitian moon sand by the way. With the subsrate i am using (jbl aquabasis), it says i need 4cm of sand on top of it, to stop nutirent leaching. But with that much sand , i am worried about gas pockets builidng up.

What does everyone suggest?

If it is fairly heavily planted you shouldn't have to worry much. The roots should take care of it. That is what I was told. It has worked for me so far.
