Thanks for reading Kara!
I may know more about physics but you know MUCH more about fish tanks.
I definitely would prefer to have that 1/2 of an inch back. I'm going to check my local PetCo when I'm home. Hopefully they will have the Red Sea Nano. I was looking for that filter before (I heard about them but couldn't remember the name).
Only a few more hours until the exam...uh oh!
