Brown sheets are generally the tougher of the two and hold together longer in the clip, which suits fish that tear at food rather than nibble.\u003c\/p\u003e\n\u003ch4\u003eDo I need a seaweed clip?\u003c\/h4\u003e\n\u003cp\u003eA clip or weight of some kind is necessary, and none is included with the 12 g or 50-sheet packs. Without one the sheet floats free within minutes and usually ends up in the overflow or against the intake strainer.\u003c\/p\u003e\n\u003ch4\u003eHow much brown seaweed should I feed?\u003c\/h4\u003e\n\u003cp\u003eOcean Nutrition's guide is roughly a 5 by 7 cm piece for an average 200 L tank, offered daily and removed after 24 hours if it has not been eaten. Adjust by how quickly it disappears rather than by tank volume alone.\u003c\/p\u003e\n\u003ch4\u003eCan freshwater fish eat this seaweed?\u003c\/h4\u003e\n\u003cp\u003eOcean Nutrition markets Brown Seaweed for herbivorous marine fish, and that is what the 31.6% protein and 6.5% fibre profile is built around. Freshwater herbivores such as plecos and silver dollars will often take it, but it is not the intended diet and freshwater-specific vegetable foods are a better fit.\u003c\/p\u003e\n\u003ch4\u003eWhy does it contain garlic extract?\u003c\/h4\u003e\n\u003cp\u003eGarlic extract is included as a feeding attractant, which is why it appears in the two-ingredient declaration alongside the seaweed itself. It is not a treatment for any disease or parasite, and no health claim is made for it.\u003c\/p\u003e\n\u003ch4\u003eHow long does an opened pack last?\u003c\/h4\u003e\n\u003cp\u003eOcean Nutrition does not publish a shelf life after opening for Brown Seaweed. In practice the limiting factor is moisture: a sheet kept sealed, cool and dry stays firm enough to clip, while one that has absorbed humidity turns soft and disintegrates in the water.\u003c\/p\u003e","brand":"Ocean Nutrition","offers":[{"title":"12g","offer_id":55293353885987,"sku":"ON1025010","price":20.95,"currency_code":"AUD","in_stock":false},{"title":"50 Sheets","offer_id":55335428161827,"sku":"ON1025017","price":111.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/on1025010_1778468139.jpg?v=1786055741","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/brown-seaweed-brown-marine-algae","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
