It self-primes, monitors its own maintenance schedule, and packs an oversized media basket so you can run mechanical, chemical, and biological filtration all at once. Available in four sizes for aquariums up to 35, 55, 75, and 110 gallons, freshwater or saltwater.

Water passes through mechanical media (to trap debris), then chemical media (to polish and remove impurities), then biological media (to grow the beneficial bacteria that process ammonia and nitrite), and finally spills back into the tank through a reversible cover. Because the pump sits at the top and is self-priming, startup is as simple as filling the chamber and switching it on.\u003c\/p\u003e\n\u003ch2\u003eFeatures — All Models\u003c\/h2\u003e\n\u003cdiv class=\"aq-features\"\u003e\n\u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eSelf-Priming Pump\u003c\/strong\u003e\u003cspan\u003eFill the chamber, plug in, and go.

A typical dose is 5 mL (one capful) per 80 L (20 US gallons) twice a week, or as needed in response to the deficiency signs above. Because trace elements are used up quickly, you can dose Flourish Trace more often than a broad-spectrum supplement without a build-up of the slower-used components.
