Glass cover for frag tank?

[Dj City]

Hello,

I set up a 20gal long frag tank and evaporation is killing me!
ATO is not the problem as it replenishes the tank but i'm using like 2+ gallons a day.
My water bill is gonna be FAT.
I will be burning through RO/DI a lot faster at this rate too.

Can I put a glass top on a frag tank to slow down evaporation?

2 gallons of evap on a 20g a day? That doesn’t seem right. However, you could add a cover. Remember it’s going to reduce your par level as it gets dirty. Get ahold of a local glass shop, let them know the size you need and you’re all good :) make sure they polish the edge on them so you aren’t dealing with raw glass corners. Also make sure you get a decent thickness so it doesn’t break, or go with acrylic.
