Source: mingllc.com (verified 2026-08-01) · corroborated by walmart.com. Ming Trading LLC's US distributor product page for the HW-304B states: "525 GPH (2000L/hr)" flow rate, "good for up to 150 gallon fish tanks", pump power "55W" stated separately from the integrated "9W" UV sterilizer bulb (55W used for wattage — the pump, not the UV lamp), a "5-stage system" with "4 media trays", and dimensions "11in L x 11in W x 17in H". Aquatic Rig's listing independently confirms a "Self-priming pump" feature (self_priming=true). Walmart's US listing confirms the $178.99 price for this exact SKU ("Pro Canister Filter Kit with 9-watt UV Sterilizer", matching the HW-304B's built-in-UV model designation, distinguishing it from the plain HW-304 without UV). No media basket volume in liters is disclosed (media is specified only by weight/count — 1lb carbon, 1lb ceramic rings, 40 bio balls), so media_capacity_l is null.
