Re: Charity ExoTerra Viv
The next important step is to drill for drainage. This allows the tank to constantly be rinsed through by pushing water through it with either an ultrasonic humidifier or a misting system such as MistKing's.
I then glue a small piece of vinal mesh over a bulkhead installed into the drilled hole so the next step, an inch or so layer of Hydroton drainage media, doesn't fall down the hole.
Over top of the Hydroton I place a layer of that vinal mesh. I find that keeps the Sphagnum moss that will go overtop of that from settling down below the hydroton overtime. this can cause the sphagnum to become sodden, compact and breakdown prematurely.
