The Blue Pet BLH-301 is a 3W hang-on-back (HOB) aquarium filter delivering up to 180 L/H, a compact, quiet filter that hangs on the rim to keep nano and small tanks clean while saving space inside the tank. It traps debris, food residue and particles for clear water, creates a gentle waterfall that oxygenates the surface, and is simple to install and maintain — an easy entry-level HOB for small setups.
Why choose the Blue Pet BLH-301?
- Compact 3W HOB with 180 L/H flow for nano and small tanks.
- Hangs on the rim — no space used inside the tank.
- Waterfall return that oxygenates the water surface.
- Mechanical + biological filtration via the filter cartridge.
- Quiet and easy to maintain.
