This model (56504) is the entry-level option in the long straight inlet range — a solid choice for smaller livewells and baitwells where a high-output pump would be overkill. If your livewell is larger or you’re keeping more fish alive for longer, step up to the \u003ca href=\"\/products\/attwood-56604-tsunami-mk2-cartridge-aerator-pump-long-straight-inlet\"\u003eAttwood 56604 Long Straight Inlet\u003c\/a\u003e for higher output in the same configuration. If clearance below the pump mount is tight and a long inlet won’t fit, the short straight inlet versions are available: \u003ca href=\"\/products\/attwood-56534-tsunami-mk2-cartridge-aerator-pump-short-straight-inlet\"\u003eAttwood 56534\u003c\/a\u003e and \u003ca href=\"\/products\/attwood-56634-tsunami-mk2-cartridge-aerator-pump-short-straight-inlet\"\u003eAttwood 56634\u003c\/a\u003e.
