The filter works well for my 40-liter tank. It’s easy to install and the water flow is steady. The sponge doesn’t harm my shrimp, and I can clean it without disturbing the fish.
Cameron Greene –
Good performance for a medium-sized tank. The wide jet pipe helps with water circulation. I liked the simple design and the fact that it doesn’t suck in small fish.

Installed it in my 60-liter aquarium and it’s been running smoothly for over a month. The filter is quiet and keeps the water clean without any issues.
