fish have been in qt for 11 days now planning on starting TTM on sat or sub for 12 days. I've got 2 -20 long and a stand that holds both one above the other. I am not using hoods but some of the comments say ich can get airborne and infect other tanks. I was planning on filling the bottom tank which is currently empty today or tomorrow. Do I need a cover? Will a cover prevent airborne ich. How common is this. Don't really want to buy a cover but will if need be.
Thanks in advance. Steve.
