A wonderful part! Perfectly conceived -

A truly great filter! Handling, mounting really awesome thanks magnet!
A star deduction there, because it is me a bit too big. So 3-4 centimeters less would better fit into a 60's pool.
The flow rate can be only slightly throttles. Therefore only suitable for fish that want a strong current.
Small neon could stick to the disk; o))
But as I said - the filter by technology a real pleasure. The water is clear!
