What size airline ? The one suggested by amazon is too small .

This air stone matches two size air tubes, 3/16 " and 3/8". Wet the airline with water. It might be easier to install.

How many leters per min?

You’re better off with the pawfly 8” cylinder. These deteriorate extremely fast as if the material they used is insufficient.

Yes they do sink. Also check out pawfly 8” cylinders. I tried the synthetic pawfly black 8” and I think its cheaply made so I’ll be sticking with the original blue 8” pawfly airstone cylinders.
