The media’s bead-like, highly porous structure promotes water flow around and through it, helping to maximize contact time without hindering circulation. This design supports clear water and helps keep nutrient levels from rising too high in a range of systems.\u003c\/p\u003e\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eRemoves phosphate and silicate from marine and freshwater aquariums with practical efficiency.\u003c\/li\u003e\n  \u003cli\u003eIrreversible binding helps minimize the chance of re-release, contributing to consistently low residual levels.\u003c\/li\u003e\n  \u003cli\u003eEffective in both fresh and saltwater, with seawater use yielding well-defined results under proper flow and dosing.\u003c\/li\u003e\n  \u003cli\u003eHighly porous, bead-shaped media that supports easy water flow and expands filtration capacity.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\u003cp\u003ePhosGuard employs a binding mechanism that captures dissolved phosphate and silicate as water passes through the media. Once bound, these compounds are held in place, reducing their availability in the main tank. In seawater, the performance is often most apparent when the media flows freely and maintains good contact with the water.\u003c\/p\u003e\n\u003ch3\u003eUsage guidelines\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eRinse PhosGuard before use to remove dust or fines, then place it so water can flow through efficiently without excessive tumbling.\u003c\/li\u003e\n  \u003cli\u003ePosition the media where the flow is strong enough to pass water through the beads, but not so turbulent that the beads collide with themselves.\u003c\/li\u003e\n  \u003cli\u003eDosage guidance: 85 mL (⅓ cup) per 200 L (50 US gallons) of saltwater or 400 L (100 US gallons) of freshwater.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePractical tips for best results\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMonitor tank parameters regularly and adjust as needed based on bioload and feeding; replace media when efficacy appears to decline.\u003c\/li\u003e\n  \u003cli\u003eFor best outcomes, integrate with routine maintenance and ensure adequate water flow through the filtration media.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhether you manage a delicate reef setup or a community tank, PhosGuard offers a straightforward option to help manage nutrient levels. Its design prioritizes passive filtration that works with your existing system, rather than requiring complex changes to routine care. Keep expectations aligned with system conditions, and consider PhosGuard as one part of a broader approach to water clarity and balance.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What does PhosGuard remove from the aquarium water?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: PhosGuard removes phosphate and silicate, helping manage nutrient levels in both saltwater and freshwater tanks.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How should I use PhosGuard in my filter?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Rinse before use, place where water flows through it, and use 85 mL per 200 L saltwater or 400 L freshwater.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Seachem","offers":[{"title":"Default Title","offer_id":57197830603129,"sku":"B000255PHQ","price":85.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/8934\/1049\/files\/seachem-phosguard-bottle-pour.jpg?v=1777738595","url":"https:\/\/petlyvox.com\/products\/seachem-phosguard-4-l-1-gal-removes-phosphate-silicate","provider":"petlyvox","version":"1.0","type":"link"}
