Beautiful condition Tetra AT-60 external filter for tropical fish tanks, with bonus item

■Overview
Used for 1.5 months. Even in a short period, minor scratches are inevitable.
I chose the AT-60 over the AT-50 because I prioritized filtration power.
The impeller blades are larger than the 50, so there is a clear difference in performance.

My Corydoras enjoyed playing in the current, and sometimes got swept away by the filter's output. It has quite a strong flow. I felt it might have been a bit too strong.
By lowering the water level slightly, you can eliminate the need for the pump's aeration.
Be careful, as it will turn into a washing machine in tanks smaller than 60cm!
However, you can naturally adjust the flow to be weaker by turning the knob.

■2 Bonus Items
Strainer not used. It's fine mesh and clogs easily, so please rinse it out about once every two weeks.
(This product does not originally come with a strainer.)
Also, I'll give you some filter floss. I feel that the effectiveness of filter media doesn't change much as long as it can filter out waste and debris.
