So trueshallow tanks are awesome for top down pics !
Imo it's kinda loud, but I have no top on the tank or doors on my stand. So I'm sure mine could be quieter. I did notice the elbow that makes the screen point up makes it louder. If you point the screen sideways it's a little quieterIs the deep blue drain fairly silent? I got the same tank a couple weeks ago at the aquarium expo. The system is also fairly similar to what I'm going to set up.
