No Daily Dosing.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eAtoll Vanadium Frag Plugs are a slow-release source of vanadium designed specifically for reef aquariums. They gradually release vanadium into the aquarium, helping maintain our target concentration of 8–10 ppb without daily liquid dosing.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Vanadium?\u003c\/h2\u003e\n\n\u003cp\u003eVanadium is a naturally occurring trace element found at approximately 2 ppb in natural seawater. Although relatively little vanadium is incorporated into the coral skeleton, much higher concentrations have been measured within living coral tissue and its symbiotic algae.\u003c\/p\u003e\n\n\u003cp\u003eAtoll targets moderately elevated vanadium levels of \u003cstrong\u003e8–10 ppb\u003c\/strong\u003e, which we have found supports fuller expansion and a healthy appearance in LPS corals.\u003c\/p\u003e\n\n\u003cp\u003eIn the aquarium, vanadium is found in detritus. This may help explain why LPS corals can develop exceptional expansion in mature, nutrient-rich reef aquariums. Atoll Vanadium Frag Plugs provide another approach: \u003cstrong\u003emaintain available vanadium while keeping nutrients and detritus under control.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eWhat should vanadium be in a reef tank?\u003c\/h3\u003e\n\n\u003cp\u003eNatural seawater contains approximately 2 ppb vanadium. Atoll recommends maintaining approximately \u003cstrong\u003e8–10 ppb\u003c\/strong\u003e when using Atoll Vanadium Frag Plugs.\u003c\/p\u003e\n\n\u003ch3\u003eWhat does vanadium do for corals?\u003c\/h3\u003e\n\n\u003cp\u003eVanadium is accumulated within living coral tissue and symbiotic algae and is believed to be involved in biological processes. Its exact role in coral or zooxanthellae (the algae inside your coral) is not fully understood. In our reef systems, we have observed improved LPS expansion when maintaining elevated vanadium.\u003c\/p\u003e\n\n\u003ch3\u003eDoes vanadium increase LPS coral expansion?\u003c\/h3\u003e\n\n\u003cp\u003eAtoll has observed fuller, more “puffy” LPS expansion when maintaining vanadium at approximately \u003cstrong\u003e8–10 ppb\u003c\/strong\u003e. The most noticeable difference can be seen in \u003cstrong\u003eAcans\u003c\/strong\u003e. In a low-vanadium environment, Acans often remain tighter to the skeleton, whereas at higher vanadium levels, they can expand significantly larger.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I dose vanadium in a reef aquarium?\u003c\/h3\u003e\n\n\u003cp\u003eAdd \u003cstrong\u003e1 Atoll Vanadium Frag Plug per gallon\u003c\/strong\u003e of aquarium water. The plugs gradually release vanadium and should be replaced approximately every three months.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need to test vanadium?\u003c\/h3\u003e\n\n\u003cp\u003eWhile not required, we recommend periodically measuring vanadium using \u003ca href=\"https:\/\/www.atollaquatics.com\/products\/oceamo-lab-ms-advanced-icp-test\" title=\"Oceamo Lab MS Advanced ICP Test\"\u003e\u003cstrong\u003eICP-MS testing\u003c\/strong\u003e\u003c\/a\u003e, particularly when first establishing the appropriate number of plugs for your aquarium. In our coral culture systems, we have maintained vanadium as high as \u003cstrong\u003e35 ppb\u003c\/strong\u003e without observing any negative effects.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use the plugs for coral frags?\u003c\/h3\u003e\n\n\u003cp\u003eYes. Atoll Vanadium Frag Plugs are designed for \u003cstrong\u003eboth maintaining vanadium and fragging\u003c\/strong\u003e, so corals can be mounted directly to the plugs while they gradually release vanadium into the aquarium.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWe recommend soaking the plugs before using them for fragging.\u003c\/strong\u003e When a dry frag plug is glued and immediately placed underwater, tiny air bubbles can escape from the porous plug and push uncured super glue toward the coral. This can potentially damage a fresh frag, particularly SPS.\u003c\/p\u003e\n\n\u003cp\u003ePre-soaking the plugs in your sump also allows a biofilm to develop, which may help reduce algae growth when the plugs are later moved to your frag rack. When you're ready to use one, simply dry the top of the plug with a towel before applying super glue.\u003c\/p\u003e\n\n\u003cp\u003eIn our heavily stocked coral propagation systems, where Atoll Vanadium Frag Plugs are used extensively, we have observed vanadium levels stabilize around \u003cstrong\u003e25–35 ppb\u003c\/strong\u003e without apparent negative effects. Our recommended target for typical home reef aquariums remains \u003cstrong\u003e8–10 ppb\u003c\/strong\u003e.\u003c\/p\u003e","brand":"Atoll","offers":[{"title":"Default Title","offer_id":47774421549315,"sku":"Atoll-BP-100","price":56.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0788\/2912\/5891\/files\/AtollVanadiumFragPlugsdosinginstructionsforreefaquariums.png?v=1787514137","url":"https:\/\/www.atollaquatics.com\/products\/vanadium-frag-plugs-reef-aquarium","provider":"Atoll Aquatics","version":"1.0","type":"link"}
