While standard HOB skimmers rely on boxy, rectangular chambers that can cause performance-robbing water turbulence, the Classic 90-HOB features a true cylindrical 4-inch reaction chamber. This architectural design, combined with a smooth conical body-to-neck transition, handles the air-and-water mixture incredibly gently. The result is a highly stable, uniform foam column that efficiently strips dissolved organic compounds out of aquariums up to 130 gallons without ever requiring a sump.\u003c\/p\u003e\u003cp\u003eDriven by the ultra-efficient \u003cb\u003eAquatrance 1000s pinwheel pump\u003c\/b\u003e, this skimmer is uniquely configured with the motor hanging externally beneath the main acrylic body. This layout ensures a remarkably slim profile that requires minimal clearance behind your aquarium glass. Additionally, the intake plumbing features a built-in surface skimmer box. By constantly drawing water directly from the surface line, it strips away the protein-heavy oil film that naturally accumulates and blocks light. With its robust cast acrylic construction, quiet air silencer, and easy-to-empty collection cup, the Classic 90-HOB delivers pristine water quality to standalone marine systems.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eTurbulence-Reducing Cylinder:\u003c\/b\u003e Circular design allows microbubbles to rise smoothly without colliding or popping prematurely.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eAquatrance 1000s Pump:\u003c\/b\u003e Pulls 420 L\/H of air while consuming an energy-saving 9 Watts of power.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eIntegrated Surface Degreaser:\u003c\/b\u003e Keeps the top of your water column pristine, maximizing gas exchange and PAR penetration.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003ePrecision Control Output:\u003c\/b\u003e A fine-tuned gate valve mechanism allows you to dictate exactly where the water line rests inside the body.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eSump-Free Adaptability:\u003c\/b\u003e The perfect elite filtration upgrade for standard, standalone rimmed or rimless saltwater aquariums.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBioload Handling\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eHeavy Bioload:\u003c\/b\u003e 60 Gallons\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eMedium Bioload:\u003c\/b\u003e 80 Gallons\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eLight Bioload:\u003c\/b\u003e 130 Gallons\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Reef Octopus","offers":[{"title":"Default Title","offer_id":50483984204024,"sku":"CLSC-90HOB","price":375.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/6909\/5160\/files\/a0dc08f0ccab43e725d8260c15668b5e.jpg?v=1789092443","url":"https:\/\/www.blueearthaquariums.com\/products\/octo-classic-90-hob-protein-skimmer","provider":"Blue Earth Corals","version":"1.0","type":"link"}
