• PhytoTank CL Copepod System


    Grow copepods using the PhytoTank (patent pending) hassle-free culture system!  The kit includes two PhytoTank-L reactors: one for growing copepods and another to grow phytoplankton to feed your copepods and coral.  This kit provides everything you need to maintain a self-sustaining copepod colony to feed your reef tank inhabitants.  You will also have enough live phytoplankton to also feed your coral.

    Features the PodNest-the combined aerator & copepod habitat.  The PodNest results in significant copepod culture density.  Also included is a large, 4-inch copepod sieve.

    The integrated LED light provides uniform lighting for maximal growth and obviates the need for space-consuming banks of fluorescent lights.  Cultures take place in disposable culture bags and our durable rubber cap has bulkheads for disposable aeration and vent tubes.  So, there is no need to extensively clean or disinfect your PhytoTank between cultures.  Simply throw out the disposable items and start your next culture.

    •Two, 3.5 Liter PhytoTank reactors

    •LED power supply

    •2-Way Power Splitter

    •LED Dimmer

    •PodNest combined aerator & copepod habitat

    Customize Your System:

    Use the Drop-Down menus to order an air pump and/or culture packs.  In addition, you can add up to two extra PhytoTanks.  These can be used to culture more copepods (remember to add another PodNest) and/or additional phytoplankton species.

    Need a Phytoplankton Starter Culture?

    Select Nano and/or Iso from the Drop-Down Menus


    Important Information about selecting starter cultures:

    Nannochloropsis Oculata:  Bright green Nano is hardy and easy to grow.  It can be refrigerated for up to 90 days and still effectively start a new culture.  After 90 days, refrigerated Nano may not start a new culture, but it is still nutritious for coral and zooplankton for up to five months.

    Isochrysis Galbana:  Golden brown Iso is often cited as particularly nutritious for bivalves.  However, it is more difficult to culture than Nano and more prone to crashing.  In addition, Iso is significantly less stable than Nano during refrigerated storage.  Consequently, we recommend starting Iso cultures immediately upon receipt.  Furthermore, since refrigerated Iso is less likely to start a new culture we recommend keeping a continuous Iso culture going to avoid having to rely on refrigerated Iso starter cultures.

    Aeration:  Vigorous aeration promotes dense cultures and prevents aggregation and settling of phytoplankton.  We provide Tetra Whisper 40 air pumps as an Add On and we will provide the appropriate air filter and valve assembly based on the number of PhytoTanks you order.

    Our Phyto Guarantee:  If you purchase a system and your culture crashes for any reason we will provide free replacement starter cultures for a $17.50 shipping and handling charge.  Simply place an order for the Starter Culture Guarantee Fulfillment on our website (https://poseidonreefsystems.com/products/starter-culture-guarantee-fulfilment)


    IMPORTANT SHIPPING INFORMATION:  Copepod systems will ship on Wednesdays and Saturdays due to timing of our cultures.  Customers located in the Northeast will receive their starter cultures with their hardware in the same shipment.  Due to repeated delays for large boxes in the USPS due to COVID-19, customers located elsewhere will receive their hardware via FedEX and the starter cultures will be shipped separately via USPS Priority mail.  All customers will receive automated emails with Tracking Numbers.  Sometimes these emails end up in your SPAM folders so please be on the lookout for that.  If you receive your starter cultures before the hardware you can refrigerate the phyto, but do not refrigerate the pods.  Keep the pods at room temperature in indirect light.  Try to start your pod cultures as soon as possible.  We normally get 7-10 days of viability for pods in our pouches.


    PhytoTank-L dimensions:  12 inches tall, 6 inches in diameter, 2lb 16 ounces when empty, working volume 3.5 Liters (118 ounces)

    The PhytoTank LED system is NOT WATERPROOF.  Do not submerge your PhytoTank.  Proper use of the disposable culture bags will prevent contamination.  If cleaning is needed wipe the PhytoTank with a damp cloth.  As with all electrical aquarium equipment keep the power supply and power cords away from water.  Create a drip loop with your power cord to prevent water from contacting the electronics.
