Amazing tank! I am just getting started with aquascaping, what is the upside down funnel with the ball thing used for/ what is in it? Thanks.

That is a Co2 drop checker. It's essential to using Co2 in your aquarium and being able to measure how much Co2 you currently have in your water column. If it's showing a blue color, then the levels of Co2 are very low. If it's showing a green color, then the tank has the perfect amount of Co2. If it's showing a yellow color then the tank has too much Co2. What's inside of it is some color changing liquid that reacts to the levels of Co2. Hope that helps!
