So I'm going away for 4 days and my ATO will normally last 3 days with my open top system. I want to lay a coupld of large sheets of transparent plastic on my tank leaving a couple of inches as a gap. Now I have dual overflow into a open top 40 gallon sump so I'm sure my oxegen levels should be fine but will closing up the top of the 6 foot tank create issues for my water in any other way? I don't want to come home to thousands of dollars worth of dead coral because I'm a bone head...lol
