Essential Copepod Food – At Scale\u003c\/h3\u003e\n\u003cp\u003eCopepods cannot survive on detritus alone. They require live microalgae to breed and thrive. A large reef tank needs a \u003cstrong\u003emassive pod population\u003c\/strong\u003e to keep sand beds clean and mandarins fed. Dosing Nannochloropsis from a 32oz bottle ensures you never under-feed your pod colony.\u003c\/p\u003e\n\n\u003ch3\u003e🪸 2. Direct Coral Nutrition for Dense Gardens\u003c\/h3\u003e\n\u003cp\u003eClams, feather dusters, gorgonians, sponges, and many LPS\/SPS corals directly consume phytoplankton. If your tank is packed with corals, competition for food is real. The 32oz size lets you feed \u003cstrong\u003eheavily and frequently\u003c\/strong\u003e without worrying about running out.\u003c\/p\u003e\n\n\u003ch3\u003e🧹 3. Natural Algae Competition – Large Volume\u003c\/h3\u003e\n\u003cp\u003eLive phytoplankton consumes the same nutrients (nitrates and phosphates) that nuisance algae and cyanobacteria need to grow. In large tanks, algae outbreaks require \u003cstrong\u003econsistent, ongoing dosing\u003c\/strong\u003e to outcompete them. A 32oz bottle keeps you in the game for months.\u003c\/p\u003e\n\n\u003ch3\u003e🥚 4. Hatchery \u0026amp; Breeding Operations\u003c\/h3\u003e\n\u003cp\u003eBreeding clownfish, seahorses, or banggai cardinals?

Example estimates:\u003cbr\u003e\n- 50-gallon tank, light feeding (5ml every other day): ~128 days (4+ months)\u003cbr\u003e\n- 100-gallon tank, standard feeding (10ml every other day): ~64 days (2 months)\u003cbr\u003e\n- 150-gallon tank, heavy feeding (25ml daily): ~12-14 days\u003cbr\u003e\n- Hatchery \/ rotifer culture: 5-14 days depending on system size\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I split the 32oz bottle between multiple tanks?\u003c\/strong\u003e\u003cbr\u003e\nA: Absolutely. One 32oz bottle is perfect for feeding a display tank + refugium + frag tank + quarantine system. Just pour needed amounts into separate small containers (use within 1-2 weeks for each opened small container).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Does the 32oz bottle need special storage?\u003c\/strong\u003e\u003cbr\u003e\nA: Same as 16oz – store unopened in cool, dark place (not refrigerator). Once opened, refrigerate. Because the bottle is larger, we recommend using a clean syringe or measuring cup to extract phyto to avoid introducing bacteria into the main bottle.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Is the 32oz bottle more concentrated than the 16oz?\u003c\/strong\u003e\u003cbr\u003e\nA: Same concentration – 200+ million cells total (approximately 6-7 million cells per ml). The value comes from the bulk price, not higher concentration.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this in a freshwater tank?\u003c\/strong\u003e\u003cbr\u003e\nA: No. Nannochloropsis is a \u003cstrong\u003emarine microalgae\u003c\/strong\u003e and will die in freshwater, clouding the tank without benefit. For freshwater, look for our Chlorella or freshwater phyto blends (sold separately).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Do I need to acclimate phytoplankton?\u003c\/strong\u003e\u003cbr\u003e\nA: No. Unlike fish or corals, phytoplankton can be poured directly into your tank or sump. No temperature acclimation required – though pouring into a high-flow area helps disperse it quickly.\u003c\/p\u003e\n\n\n","brand":"AquaReefNY","offers":[{"title":"Default Title","offer_id":46976911933611,"sku":"phyto32","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/9443\/6523\/files\/phyto32.png?v=1778725534","url":"https:\/\/aquareefny.com\/products\/live-phytoplankton-nannochloropsis-32oz-bulk-size-for-large-reef-tanks-heavy-feeding","provider":"AquaReefNY","version":"1.0","type":"link"}
