Widely regarded as a workhorse filtration unit for entry-level and experienced reef keepers alike, the Classic 110-INT seamlessly balances cost-effectiveness with industrial-grade engineering. Powered by the specialized \u003cb\u003eAquatrance 1000s pinwheel pump\u003c\/b\u003e, it draws a massive amount of air relative to its low power draw, producing the ideal bubble size needed to pull dissolved organic compounds from the water column before they can break down into unwanted nitrates and phosphates.\u003c\/p\u003e\u003cp\u003eConstructed from premium, heavy-duty cast acrylic, this internal skimmer features a smart hybrid cone body that tapers toward the top. This specialized shape naturally reduces internal turbulence, allowing the rising foam to stabilize and concentrate as it journeys into the collection cup. A precision gate valve assembly gives you absolute control over the internal water line, allowing you to easily adjust between dry and wet skimming depending on your system's bioload. Backed by a bubble plate diffuser that reduces micro-bubble bypass into your return pump chamber, the Classic 110-INT is an exceptionally reliable asset for any standalone marine display.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eReliable In-Sump Profile:\u003c\/b\u003e Streamlined footprint leaves plenty of space in your filtration chamber for media reactors or refugiums.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eAquatrance 1000s Pump:\u003c\/b\u003e Draws a robust 420 L\/H of air while consuming an energy-saving 9 Watts of electricity.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eBubble Diffuser Plate:\u003c\/b\u003e Quiets the internal water churning, allowing bubbles to lift smoothly without popping prematurely.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eEasy Adjustment Gate Valve:\u003c\/b\u003e Raised gate valve system lets you make micro-adjustments to the internal water level without splashing.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eEffortless Cup Maintenance:\u003c\/b\u003e Features a secure, quick-release neck seal so you can pull the cup for emptying without struggling.\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 90 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\u003ch3\u003eIdeal For:\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eReef and saltwater systems from 60 to 130 gallons running a sump with 7–8 inches of available water depth.\u003c\/li\u003e\n\u003cli\u003eHobbyists stepping up from a hang-on-back skimmer to their first in-sump unit.\u003c\/li\u003e\n\u003cli\u003eSump builds where a compact-footprint in-sump skimmer with a reliable gate valve and quick-release cup is preferred.\u003c\/li\u003e\n\u003cli\u003eSystems where microbubble control is a priority, such as tanks with large open sump-to-display flow.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePro Tips:\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSet the gate valve slowly and give the skimmer time to respond.\u003c\/strong\u003e The gate valve controls the water level inside the skimmer body, and small adjustments have a delayed effect as the body stabilizes. Make a small adjustment, then wait 15–20 minutes before evaluating the result. Rapid back-and-forth changes during break-in are the most common cause of frustration with in-sump skimmers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMeasure your sump water depth before purchasing.\u003c\/strong\u003e The Classic 110-INT requires 7–8 inches of water in the skimmer chamber to operate correctly. Too shallow and the pump inlet comes out of the water; too deep and the body sits too high, pushing water over the neck. Most standard sumps accommodate this range, but verify before installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eUse the cup drain to establish a routine emptying schedule.\u003c\/strong\u003e The drain port on the collection cup makes it practical to run a small-diameter tube from the cup to a waste container and empty it on a schedule rather than waiting for the cup to fill. This keeps skimmate from overflowing and keeps the neck cleaner, which improves foam consistency over time.\u003c\/p\u003e","brand":"CoralVue","offers":[{"title":"Default Title","offer_id":47322740064425,"sku":"CLSC-110INT","price":326.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0021\/4958\/0912\/files\/2b9801f348b14fafe1d430d1ea8d7fcb.jpg?v=1786227824","url":"https:\/\/worldwidecorals.com\/products\/clsc-110int","provider":"World Wide Corals","version":"1.0","type":"link"}
