Who all uses lids on their Reef?

[FredsNJReef]

Absolutely have one and always will as long as fish are in my tank(s).
I have a clear mesh top on my Fusion Nano 20 with 1/4 inch gap on the sides. I must have not centered it one night and when I came home from work my beautiful and happy purple Firefish was on the ground next to the tank :-(

got my octolid from @cromag27 and couldn’t be happier. Great quality and super clean fit. Octo aquatics is a great place to buy a lid [emoji1360]
