DIY divider for a 45 gallon

[NCStateFisher]

This may sound like a really dumb question, but what would you all recommend to use to make a divider for a 45 gallon tall, i need to make something about 22" tall and 12" wide but would really like to have something thats kinda like mesh rather than acrylic or anything like that

I use the white egg crate/light diffuser found at the hardware store. It works pretty well.

I agree. Remember that the employees will probably know it as "light diffuser", if they even know what it is.
