It provides a dedicated chamber for flow-through filter media.\u003c\/p\u003e\u003ch3\u003eFrançois Neo’s recommendation\u003c\/h3\u003e\u003cp\u003eI add a reactor to address a measured need. Choose the medium first, calculate its dose for your aquarium, then set the flow according to that medium’s instructions. Carbon, phosphate-removing media and biopellets have different operating requirements; chamber capacity alone does not determine the right dose or flow.\u003c\/p\u003e\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eMR 100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConstruction\u003c\/th\u003e\n\u003ctd\u003eAcrylic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eChamber capacity\u003c\/th\u003e\n\u003ctd\u003e1,500 mL \/ 1.5 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer aquarium guideline\u003c\/th\u003e\n\u003ctd\u003eUp to 500 L \/ approx. 132 US gallons\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSuggested feed-pump rating\u003c\/th\u003e\n\u003ctd\u003e2,000 L\/h \/ approx. 528 US GPH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e152 × 152 × 365 mm \/ approx. 5.98 × 5.98 × 14.37 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWater type\u003c\/th\u003e\n\u003ctd\u003eMarine or freshwater\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003csmall\u003eThe aquarium-volume figure is a manufacturer guideline.
