Why not connect it directly to your large rodi container where you store rodi for mixing new water?
My first 2 years into the hobby i used to have a separate top off container and it was extra work. You would need to fill it up every week if not more on a large setup.
After that i just hook the top off pump to the large 50g brute where i store rodi water and never look back again. Never need to worry about top off container being dried.
