32 oz Freshwater Copepod Culture 16 oz Freshwater Phytoplankton Blend

DescriptionFreshwater Copepods & Phytoplankton Combo – Synergistic Feeding SystemWe pair a 32oz copepod culture with a 16oz phytoplankton bottle, specifically tuned for copepod-dominant systems where phytoplankton serves as the primary nutritional driver. Copepods consume 5-20 algal cells per minute depending on size, life stage, and food availability. Our 32oz copepod shipment (8,000-15,000 individuals) matches perfectly with 16oz phytoplankton (2-3 million cells/ml)—delivering a pre-balanced ecosystem requiring minimal adjustment upon setup. Both components are cultured within 3 days of each other, ensuring synchronized maturity and natural population equilibrium.This combo excels in systems where fry benefit from established copepod populations plus reliable phytoplankton nutrition without requiring separate daphnia cultures. Copepods provide substrate dwelling, biofilm cleaning, and continuous background food; phytoplankton sustains reproduction and population growth. We hand-inspect both bottles together to verify density matching—if copepod or phytoplankton count falls below threshold, the entire pair is recultured before shipment. This synchronization eliminates guesswork when setting up new fry systems.System Setup & FeedingDistribute 32oz copepods across 20-30 gallon fry system or split between two 10-15 gallon containers. Add 16oz phytoplankton as initial food source. After 3 weeks, dose 3-5ml phytoplankton weekly to maintain copepod reproduction and population density. Perform 20% water changes bi-weekly. Temperature: 68-76°F. Expected outcome: copepod population reaches 2,000-3,000 individuals per gallon within 6-8 weeks, sustaining fry continuously.Who This Is ForSerious breeders preferring copepod-centric systems, fry tank operators seeking simplicity without multiple culture types, and aquaculturists wanting guaranteed ecosystem balance from day one.FAQsQ: Why choose this over individual copepod and phytoplankton bottles?A: Synchronized density guarantees population equilibrium. Buying separately risks receiving suboptimal copepod or phytoplankton batches—this combo ensures compatibility.Q: Can I add daphnia to this system later?A: Yes. Copepods and daphnia coexist in aquariums. Add Freshwater Daphnia 32oz after 2 weeks for diversified fry food without destabilizing existing copepod populations.Why This Combo Outperforms Separate PurchasesFreshwater copepods depend on phytoplankton as their primary food source. When you buy them separately, there is often a gap between introduction and feeding — that delay can crash a new copepod population before it establishes. This combo ships copepods already conditioned on our phytoplankton blend, and includes a separate 16oz phytoplankton bottle for ongoing feeding once introduced to your tank. The result is faster colony establishment and higher survival rates compared to adding unfed copepods to a bare tank. Our customers who switched from separate purchases to this combo report 30-50% better pod retention after the first week.Recommended SetupIntroduce copepods first, allow 24 hours to settleDose 1-2 capfuls of phytoplankton every 2-3 daysMaintain temperature at 68-78°F for optimal reproductionAvoid copper-based medications in destination tanksPair with Freshwater Phyto Culture Kit to grow unlimited phyto at homeStore both bottles refrigerated at 50-65°F upon arrival. Phytoplankton keeps 3-4 weeks refrigerated; copepods are healthiest when introduced within 5-7 days of delivery.You May Also LikeFW Copepods only — 32ozFW Phyto only — 16ozEcosystem Starter Pack — 5 live cultures
