Advice for my first Walstad tank
Hello, so I set my first Walstad up recently but I’m concerned my sand cap is too thick. The grain size is .5mm-1mm.
I am noticing some trapped gas which I am releasing with my extra long tweezers (it doesn’t smell, tank is 3 weeks old)
Any advice for a newcomer?
UPDATE
Alright so update for anyone that’s interested:
I fixed the cap thickness.
So, there’s no livestock in here at the moment so even if I f*ck it up I figured I can’t kill anything so what’s the harm?
Anyway, the original sand cap was 1.5inches give or take and after emptying the tank, removing all plants and wood I have managed to reduce the cap all over the tank to 0.8inches give or take.
Thanks to everyone for the advice they gave it was very much appreciated.
