NF Top Filter (3-Layer Slim) for 1.5ft Tanks

Overhead trickle filters like this slim three-layer unit are a practical, time-tested choice for many Singapore fishkeepers. Sized for a 1.5ft tank, it sits on the rim and rains water back through stacked media trays, giving you generous space for sponge, biological rings and carbon in an easy-to-service format. Because the media is exposed to air as water trickles through, you get strong oxygenation, which is welcome in our warm 27-29C water where oxygen levels drop more easily.

Top filters are simple to maintain, which is part of their appeal: lift the lid, rinse or swap a layer, done. That makes them friendly for newer keepers and for anyone who wants reliable mechanical and biological filtration without wrestling a canister. Keep the return spray gentle for shrimp or bettas, and rinse media in old tank water so you do not wipe out your beneficial bacteria.
