Price: ₹401.00 · Out of stock

The Blue Pet BLH-401 is a 4W hang-on filter rated 250 L/H. It sits between the BLH-301 nano and full SunSun HOB/canister options when you need a bit more polish on a small planted or community tank. Listed specs: 4W · 250 L/H · small HOB. Tanks that outgrew the 301 but still cannot justify a YBF-500 hang-on canister. Hang, fill, start, then tune the tap. Confirm the clip on your glass thickness before you order. Rinse mechanical media on a short interval. HOB weirs overflow when pads cake. Smaller: [BLH-301](/product/bluepet-blh-301-hang-on-filter). Larger hang-on canister: [YBF-500](/product/sunsun-ybf--500-hangon-filter). ## FAQ **Litter vs litre?** The carton sometimes prints “Litter/Hr”. Flow is 250 litres per hour. **301 or 401?** Pick 401 if the 301’s 180 L/H already feels weak or the pad clogs daily. **Surface film?** Keep the water level at the weir and clean the skimmer slot. **Livestock?** Fine for community fish. Shrimp want an intake sponge. Aquaroutine ships this SKU across India with a GST invoice. Match the wattage, flow, and footprint to your tank before you add livestock or dense stems. If a number on the carton disagrees with this page, trust the model printed on the housing and write to support with a photo of the label. We stock this as a repeatable equipment SKU, not a one-off stone — use the listing specs when you compare hang-on, canister, light length, or sponge size against the tank you already own.
