Blue Pet BL-883W Hang-On Top Sump Filter 12 Watts 800L/H
The Blue Pet BL-883W is a hang-on-top sump filter delivering up to 800 L/H from a 12W pump, replicating a full sump system’s capacity while mounting discreetly above the tank — no plumbing, no cabinet space. Its spacious clear chamber holds multi-stage media trays for superior mechanical, chemical and biological filtration, and a rotating bio-wheel aerates the water as it returns. Ideal for heavily stocked small-to-medium aquariums.
Why choose the Blue Pet BL-883W?
- Sump-grade capacity in a hang-on-top unit — no plumbing required.
- Spacious multi-stage media trays for mechanical, chemical and biological filtration.
- Rotating bio-wheel aeration for strong oxygen exchange.
- Great for heavily stocked tanks that need extra filtration.
- Overhead design frees up space inside the tank.

Which tanks is it best for?

How to set it up
Sit the filter on top of the tank, load the media trays (mechanical first, then chemical and biological), prime the pump and plug in. Keep it running 24/7, and rinse the mechanical media in old tank water (never tap water) when flow slows. See how to install an aquarium filter and filter media guide.
Frequently asked questions
What size tank is the BL-883W for?
Medium tanks up to roughly 200L, based on its 800 L/H flow.
What is the bio-wheel for?
The rotating wheel exposes beneficial bacteria to air and water, boosting oxygen and biological filtration.
Do I need plumbing like a normal sump?
No. It hangs on top of the tank with no drilling, plumbing or cabinet space.
Is it good for heavily stocked tanks?
Yes. The large media chamber and 800 L/H flow handle higher bio-loads well.
How often should I clean it?
Rinse the mechanical media in old tank water when flow drops, usually every 2–4 weeks.
