IM 100EXT what you wished you did

[HonorableWhat]

So!
I just ordered the I'm 100g ext after I'm had their summer sale.

I'm upgrading from a 40g and was wondering.

What's some things you wished you had done with the tank before it was filled and stocked?

Basically just trying to pick brains for ideas takey life easier once I'm up and running

Wire everything up nicely beforehand.
