Welcome to TRT! May I suggest arranging the rock so it isn't touching the glass. Easy to clean and I just don't trust the cubes or aquapods when it comes to having rock on the glass. Heard to many stories of the tanks busting. I have both the aquapod 24 and 12 gallon jbj and I try to keep the rock away from the glass.
Congrats on the new tank.
I have a 12 gallon and love it. It has taken 10 months for it to become the way I like it.
Patience is a very big key to nano tanks.
I agree with the rock not touching the glass. It is a lot easier to clean that way too.
