I have ran by the thumb rule in dirted tanks of no more than 1-1/2" but I see some people pile Aqua Soil (pebble style soil) up to 4" deep in some mounded areas...can "pebble soil" be piled deeper because it aerates better??
Does anyone at least know if I should use a rock or gravel bases/core when building "mounds" ?
