want to ask all sifu, I want to put Eheim 2215 as the filter of my 2x1x1 tank.

Shall I cover the inlet with mosquito nest to prevent my cherry shrimp from sucking into the filter?

I notice the outlet has a tube with many hole and a L tube. which one shall I put as the outlet? The hole tube is quite long, If I put it vertical, part of the tube will be expose in air? or put it horizontally?

successfully put on the 2215. But the output wave (using the hole tube) like tsunami in my 2x1x1 tank. Is it possible to reduce the speed of the current?
