Perfect for a 20 gallon
These things are great if you know how to read the instructions. I have two of them for my rimless 20 gallon tank and they keep the water level at par for a week. I'm using the recommended Evian 1L bottles.

Wast of money
This was a wast of my money. It will only fit on tanks without any type of rim. It pops off easily and then you have spilled water to clean up.

Wonderful thing!!
I run both fresh water and marine reef tanks. Mind this is just for smaller tanks, but it makes life so much easier. You need to get one!!

Very useful!
This was surprisingly sturdy. It helped relieve my stress on a weekend trip. My water level evaporates so quickly
