Dry start with which substrate?
Hi guys, I have a friend who's starting a 2.5 gallon dry start with some MM but I dont know what to recommend her. She's hoping to have a couple of OEBT after several months. Should she go with top soil, capped with sand for the dry start or go for something like amazonia, fluval SS, or akadama? What would be the best substrate for dry start and OEBT?
