Lee’s Undergravel Filter

A Lee's undergravel filter plate sits beneath the gravel and draws water down through the whole substrate, turning the gravel bed itself into a large biological filter.

Key features

• Uses the gravel bed as a broad biological filter
• Driven by an air pump or powerhead (sold separately)
• Simple, quiet filtration with no cartridges to buy
• A long-proven approach for community aquariums

Undergravel filters suit fish-only community tanks; they are not the best match for heavily planted tanks or fine sand, where a canister or hang-on filter is easier to manage. More aquarium accessories. Available for local pickup at our Lethbridge store.
