During break-in the skimmate will likely be wet and light-colored. Set the water level adjustment to mid-range and leave it alone for the first two weeks before making changes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeep the Aquatrance 1000s air intake clear. \u003c\/strong\u003eThe external pump mounting makes it easy to check and clean the venturi air intake regularly. A partially blocked intake reduces air draw and noticeably drops skimming performance without any other obvious symptoms. The included air silencer should be removed and rinsed periodically.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatch the skimmer to your actual bioload, not just tank volume. \u003c\/strong\u003eA heavily stocked fish-only tank at 75 gallons will push this skimmer harder than a lightly stocked reef at 105. Use the bioload table above as your primary sizing reference, not the maximum tank rating.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003c\/div\u003e","brand":"CoralVue","offers":[{"title":"Default Title","offer_id":47322739998889,"sku":"CLSC-100HOB","price":334.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0021\/4958\/0912\/files\/550215c2160b32bd5b4f430f99459930.jpg?v=1786227823","url":"https:\/\/worldwidecorals.com\/products\/clsc-100hob","provider":"World Wide Corals","version":"1.0","type":"link"}
