Dose 5 mL (one capful) per 80 L of tank water, twice a week. Scale down for smaller tanks — 40 L takes 2.5 mL, a 200 L tank takes 12.5 mL. Dose the display tank directly; it is not a water-change conditioner and does not need to be added only when you change water.\u003c\/p\u003e\n\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\n\u003cp\u003eSuitable for freshwater community, planted and African cichlid aquariums on a normal dosing and water-change routine. Formulated for freshwater systems only — it is not the marine equivalent, and should not be used to supplement a saltwater or reef tank. Seachem's own guidance treats shrimp and snails as more sensitive than fish to this category of supplement: start at a partial dose and work up to the full rate gradually rather than dosing a shrimp tank at full strength from day one. The copper included is at a low enough level that it is not expected to stress invertebrates at the recommended dose, but a gross overdose should still be avoided.\u003c\/p\u003e\n\u003ch3\u003eCare and considerations\u003c\/h3\u003e\n\u003cp\u003eIt is typically unnecessary to run more than one trace element supplement in the same tank at once — Fresh Trace is safe to use alongside other Seachem freshwater trace products (Cichlid Trace, Discus Trace, Flourish Trace, Gold Trace), but doubling up rarely adds anything. If you also dose a non-Seachem trace supplement, check both labels for overlap and leave a gap between the two rather than dosing them together.\u003c\/p\u003e\n\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\n\u003cp\u003eCovered by Seachem's standard product guarantee in addition to your rights under Australian Consumer Law. Standard shipping applies — this is a compact liquid additive with no special freight handling.\u003c\/p\u003e\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\u003ch4\u003eWill Fresh Trace affect my pH, KH or GH?\u003c\/h4\u003e\n\u003cp\u003eNo. It contains no buffering agents or acids, so it won't move pH or KH, and the mineral concentration is too low to affect GH under normal dosing.\u003c\/p\u003e\n\u003ch4\u003eIs it safe for shrimp and snails?\u003c\/h4\u003e\n\u003cp\u003eYes, at the recommended dose, though Seachem treats invertebrates as more sensitive than fish to this category of product — start with a partial dose and increase gradually rather than dosing a shrimp tank at full strength immediately.\u003c\/p\u003e\n\u003ch4\u003eCan I use it in a marine or reef tank?\u003c\/h4\u003e\n\u003cp\u003eNo. Fresh Trace is formulated specifically for freshwater systems. Marine tanks need Seachem's separate marine trace element product.\u003c\/p\u003e\n\u003ch4\u003eDo I still need it if I already dose Flourish?\u003c\/h4\u003e\n\u003cp\u003eUsually not both at full rate — running two trace element products at once is typically unnecessary. Fresh Trace is safe alongside other Seachem trace products, but check you're not duplicating the same elements before dosing both.\u003c\/p\u003e\n\u003ch4\u003eHow long will a bottle last?\u003c\/h4\u003e\n\u003cp\u003eAt the standard rate of 5 mL per 80 L twice weekly, a 250 mL bottle covers roughly 25 weeks on an 80 L tank; a 4 L bottle covers the same tank for around 400 weeks. Larger tanks use proportionally more per dose, so the bottle empties faster.\u003c\/p\u003e","brand":"Seachem","offers":[{"title":"250 mL","offer_id":55244173967651,"sku":null,"price":26.95,"currency_code":"AUD","in_stock":true},{"title":"500 mL","offer_id":55244174000419,"sku":null,"price":42.95,"currency_code":"AUD","in_stock":true},{"title":"4 L","offer_id":55244174033187,"sku":null,"price":270.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/0719-fresh_trace_4_l_9ce3fabf-b167-48e0-ade9-8cfabedb4b09.png?v=1782710724","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/seachem-fresh-trace","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
