Wow, the shimmer lines on the back are just icing on the cake, how did you get your aquaclear intake tube so clear?
I've got a test tube from the pharmacy and bought a diamond grinder!
the test tube has a diameter of 16mm.
at the rounded part I then cut slits pure.
and then put on the clear aqua.
I write with the google translated .....
look here. maybe this will help you ....
