Grow copepods and phytoplankton hassle-free using the PhytoTank CL System! This kit includes everything you need to maintain a self-sustaining copepod colony to feed your reef tank inhabitants. It includes two PhytoTank-L reactors: one for growing copepods and another for growing phytoplankton to feed your copepods. You can also use any excess phytoplankton to feed your corals!**

The kit features the PodNest-- a combined aerator and copepod habitat which results in significant copepod culture density. Also included is a large, 4 inch copepod sieve to help catch copepods.

The integrated LED light provides uniform lighting for maximum growth and eliminates the need for space-consuming banks of fluorescent lights. Cultures take place in disposable culture bags, and the PhytoTank`s durable rubber cap has bulkheads for disposable aeration and vent tubes, so you wont need to extensively clean or disinfect your PhytoTank between cultures. Simply throw out the disposable items and start your next culture!

Product Questions

If this is BRS Recommended.... Why isn't there an explanation or a video describing why its recommended? Honest question, Not trying to sound like a brat. Its just rather difficult to be willing to buy this when I can hardly find anything on it other than Poseidon Systems own website.
Question by: Theodore Grissom on Aug 18, 2022, 8:40 AM
Hi Theodore. Thank you for the recommendation. Our video team works hard to bring out as much content as they can produce and appreciate the recommendations provided, we will submit your suggestion for their consideration. Stay tuned.

Is this actually self sustaining or do you have to feed them directly? I've never done this before. Does it take water from my tank or anything and use the nutrients in it to do that? Super interested!
Question by: Derrick Loughlin on Jul 6, 2022, 11:31 AM
Thanks for the question! It is hard to answer this as it is entirely self-sustaining. The systems don't need extra components, however, you will need to provide fertilizer to promote robust phytoplankton growth and then add some phytoplankton to the pod culture vessel to feed the copepods. Let us know if we can help with anything else!

Where can you buy the fertilizer that is included in the kit? Or suggest a replacement.
