Hi,
It is said and I've seen with my own eyes and nose[P], a well oxygenated substrate [via plant roots using powersand will not be smelly[rotten egg] if you poked your finger deep in the soil to smell. Ordinary sand+base substrate that's been setup for more than 2-3 months will.
Soil will degrade, and the answer is to top up. i've done more than 2 rescaping of soil tanks and it's a lot of work. removing the fine roots that may rot etc. Finishing up by doing a top up of new soil and gentle 'WIWO'-water in water out. Fresh water in one side and cloudy out the other.
