Pre-wet it by adding it to a double volume of freshwater (500 mL), then rinse before placing it in the filter. For ongoing control, continuous use of small quantities is preferable to intermittent use of larger quantities.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDosage\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUse 85 mL (1\/3 cup) for every 200 L (50 US gallons) of saltwater or 400 L (100 US gallons) of freshwater. Leave in place for 4 days, then test phosphate or silicate. If the target level has not decreased to around 0.02 mg\/L, replace the media; otherwise, leave it in place until levels begin to climb again. Do not over-treat.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSeachem PhosGuard phosphate and silicate-removing filter media.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan Seachem PhosGuard be used in freshwater and marine tanks?\u003c\/strong\u003e\u003cbr\u003e\nYes. It is intended for both freshwater and marine aquaria, but it is not recommended for phosphate-buffered freshwater.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much PhosGuard should I use in a saltwater aquarium?\u003c\/strong\u003e\u003cbr\u003e\nUse 85 mL (1\/3 cup) per 200 L (50 US gallons) of saltwater.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much should I use in freshwater?\u003c\/strong\u003e\u003cbr\u003e\nUse 85 mL (1\/3 cup) per 400 L (100 US gallons) of freshwater, provided the aquarium is not phosphate-buffered.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhen should I replace the media?\u003c\/strong\u003e\u003cbr\u003e\nAfter 4 days, test phosphate or silicate. Replace it if the level has not fallen to around 0.02 mg\/L; otherwise, keep it in use until levels rise again.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan PhosGuard be regenerated by baking it?\u003c\/strong\u003e\u003cbr\u003e\nNo. Aluminium oxide is not regenerable by baking. Drying the media does not restore its phosphate-removal capacity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use PhosGuard in a reef aquarium?\u003c\/strong\u003e\u003cbr\u003e\nThe manufacturer’s controlled testing found no detectable soluble aluminium released from alumina under reef conditions near pH 8. Low pH and high dosage levels can release soluble aluminium, so follow the stated dosage and avoid over-treating.\u003c\/p\u003e","brand":"AD","offers":[{"title":"100ml Bagged","offer_id":39279164981302,"sku":"000116018500","price":193.0,"currency_code":"ZAR","in_stock":true},{"title":"250ml","offer_id":39279165014070,"sku":"000116018609","price":237.0,"currency_code":"ZAR","in_stock":true},{"title":"500ml","offer_id":39279165046838,"sku":"000116018302","price":403.0,"currency_code":"ZAR","in_stock":true},{"title":"1L","offer_id":39279165079606,"sku":"000116018708","price":661.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0151\/9016\/3510\/files\/SeachemPhosguard100mlbagged.jpg?v=1744103719","url":"https:\/\/jungleaquatics.com\/products\/seachem-phosguard","provider":"Jungle Aquatics Pet Store","version":"1.0","type":"link"}
