For daily dosing, add the powder directly into an area of good flow. For weekly dosing, dissolve in a bucket of aquarium water first, then add gradually. Use 1–2 g per 100 L as a starting point, and test all three foundation elements weekly — if one drifts out of line with the others, correct it with the individual Foundation A, B or C liquid rather than increasing the ABC+ dose.\u003c\/p\u003e\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable for:\u003c\/strong\u003e reef aquariums with moderate, balanced calcium\/alkalinity\/magnesium demand — mixed reefs and systems without heavy, lopsided SPS growth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e systems where one element consistently depletes faster than the others — dosing more ABC+ to correct it will overdose the other two.

The liquid 3-pack lets you dose and correct each element on its own, which matters if your tank consumes them unevenly.\u003c\/p\u003e\u003ch4\u003eHow long will 1 kg last?\u003c\/h4\u003e\u003cp\u003eAt the conservative end of the 1–2 g per 100 L range, a 1 kg tub covers roughly 50,000 L of cumulative dosing — several months on a typical home reef.\u003c\/p\u003e\u003ch4\u003eShould I dose daily or weekly?\u003c\/h4\u003e\u003cp\u003eEither works. Daily dosing keeps levels more stable; weekly dosing (pre-dissolved in a bucket) is simpler to fit into a routine. Test weekly regardless of dosing frequency.\u003c\/p\u003e\u003ch4\u003eWhat if my calcium keeps dropping faster than alkalinity and magnesium?\u003c\/h4\u003e\u003cp\u003eDon't increase the ABC+ dose to compensate — that will overdose alkalinity and magnesium. Correct calcium on its own with Foundation A liquid instead.\u003c\/p\u003e\u003ch4\u003eIs 1 kg or 5 kg better value?\u003c\/h4\u003e\u003cp\u003eBoth work out to under 1c per litre dosed. Choose 5 kg only if you're confident you'll use it within its shelf life — the powder is hygroscopic and best used within a reasonable time of opening.\u003c\/p\u003e","brand":"RedSea","offers":[{"title":"Default Title","offer_id":54774153871651,"sku":"RED300","price":48.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/Red_Sea_Foundation_ABC_skeletal_elements_8f97c9ed-a476-4339-83b1-40f4f0334a5d.jpg?v=1782112619","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/red-sea-reef-care-skeletal-elements-foundation-abc-1kg","provider":"Nicks AOT","version":"1.0","type":"link"}
