Manufacturer information

Poseidon Reef Systems was founded by a biochemist and reef hobbyist. He developed the PhytoTank system with the goals of saving space, energy, time, and money while culturing and dosing phytoplankton and copepods. Every element of the design was evaluated using the scientific method to consistently grow dense phytoplankton and copepod populations to feed a reef tank.

Yes, I would recommend this.

Easiest way to make phyto

Pros: Easiest and cleanest way to culture microalgae

Cons: None

I have been using these to grow T-iso for over 3 years now. Easiest way to grow micro algae. Very clean, no contamination problems, and can be hidden anywhere. If you want to attempt clownfish breeding this will help your success rate. If you want to simply add a DHA or EPA food source to certain reef inverts there is not easier live option. Maintenance is under 10 minutes a week.
