Dissolve in at least one cup of freshwater. Check alkalinity every 2 weeks and adjust dose or frequency accordingly.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eADVANCED:\u003c\/strong\u003e Check alkalinity, then follow dosing regimen above until alkalinity is adjusted to 4-5 meq\/L. Each dose will raise alkalinity by about 0.25 meq\/L. Size or frequency of dose can be adjusted, but do not exceed 1 meq\/L per day. Thereafter, use as required to maintain alkalinity.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eEXPERT:\u003c\/strong\u003e After determining the alkalinity consumption rate, set up a continuous drip system. Use the following formula to determine how much to add to your top-off water: t=0.05va (t=teaspoons to add to top off water, v=volume of tank in gallons, a=amount to raise alkalinity in meq\/L). For example, if you want to raise your alkalinity by 1 meq\/L in a 50 gallon tank, then you would add 0.05x50x1=2.5 teaspoons into the top-off water.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eHINTS:\u003c\/strong\u003e Use MultiTest:Marine pH \u0026amp; Alkalinity to measure total alkalinity.\u003c\/p\u003e","brand":"Seachem","offers":[{"title":"Seachem Reef Builder 300g (366)","offer_id":45676900450477,"sku":"SEACHEM-43734","price":9.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0543\/0391\/6205\/files\/reef-builder.jpg?v=1769161699","url":"https:\/\/aquagroup.co.uk\/products\/seachem-seachem-reef-builder-for-coral-growth","provider":"Aqua Group","version":"1.0","type":"link"}
