The NF Mini Bubble Filter for SG Nano and Shrimp Tanks

This air-driven mini filter is one of our go-to recommendations for the small tanks so many Singapore keepers run on a desk or shelf. Powered by an air pump rather than a motor, it pulls water through a sponge that traps debris and hosts the beneficial bacteria a nano relies on, all while running quietly. The gentle, low flow is exactly what delicate stock wants, which is why it’s a favourite for betta, shrimp and fry tanks where a strong current would stress the inhabitants.

For shrimp keepers it has an extra advantage: the sponge intake won’t suck in shrimplets the way a powered filter can. In our warm climate the steady aeration also helps keep dissolved oxygen up in a small water volume. Rinse the sponge in old tank water during maintenance so you preserve the bacterial colony, and the suction cup makes repositioning simple.
