I'll be removing the lids once I find a way to reduce my humidity, my house hits 60 - 70 % with them off and around 50 with them on. I'll likely do a humidistat connected to a bathroom fan venting outside.
As for a FTS, It's really embarrassing right now due to the amount of Cyano and lack of fish... Once I get that under control and the area cleaned up a bit there will be a FTS 
The aluminum cantruss is really nice to work with, it has so many options I'm suprised it's not more popular. It also acts as a heatsync, so I dont need to use any fans! Lights peak at 110F.
