Filtration Unit 500x300x300 ◇ For Overflow Aquarium

This is a filtration system for an overflow aquarium, custom-made 3 years ago.
Size: 500x300x300

It was used without any issues until recently, but I am selling it as I am retiring from keeping aquariums.

I am also selling the 60cm overflow aquarium tank separately.
If you are considering purchasing them as a set, please take a look at that listing as well.
