Dosing is calculated from your measured phosphate reading rather than applied on a fixed schedule, so testing before every dose isn't optional.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTargeted phosphorus source\u003c\/strong\u003e — for reef systems where phosphate has fallen below a healthy working range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDose calculated from your test result\u003c\/strong\u003e — not a flat daily dose; you measure, then dose to the number.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePairs with bacterial dosing\u003c\/strong\u003e — Continuum recommends using it alongside BacterGen•M, BacterGen•MD or BacterClean•M for bacterial support, and with ULNS Nitro if nitrogen is also running low.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced hobbyist product\u003c\/strong\u003e — intended for reefers already running a ULNS system and comfortable testing regularly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnder 1c per litre\u003c\/strong\u003e — at Continuum's reference dosing rate, the 500 mL bottle works out to under 1c per litre of tank water treated.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eComplex inorganic phosphorus supplement for phosphate-limited reef systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eActive constituents\u003c\/th\u003e\n\u003ctd\u003eContinuum describes this as a complex inorganic phosphorus source (\"phosphorus compounds\"); a full ingredient breakdown is not published\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTarget phosphate level\u003c\/th\u003e\n\u003ctd\u003eApproximately 0.02 ppm in the aquarium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePack size\u003c\/th\u003e\n\u003ctd\u003e500 mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSuitability\u003c\/th\u003e\n\u003ctd\u003eMarine and reef aquaria running ultra-low-nutrient systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCost per litre\u003c\/th\u003e\n\u003ctd\u003e500 mL: under 1c per litre, based on Continuum's reference dose of 5 mL per 100 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eDosage and directions\u003c\/h3\u003e\u003ch4\u003eHow much do I dose?\u003c\/h4\u003e\u003cp\u003e5 mL raises phosphate by approximately 0.01 ppm in 100 L (25 US gallons).
