The Red Ogo Gracilaria parvispora is an exceptionally beautiful macroalgae. Between bright red and burgundy in hue and graced with short bushy fronds, it adds a splash of color and texture to any refugium or saltwater aquarium.

Perfect for surgeonfish and other herbivorous species, this macroalgae grows quickly in a refugium so you can harvest the growth for supplemental feeding.


  1. Free of Parasites
    All of our macroalgaes are kept in their own closed system. They are cleaned, treated, quarantined, and inspected before they are sent to you. This ensures that no unwanted pests & parasites make it into your tank.
  2. Add Color & Texture
    Red Ogo`s bright red & burgundy hue with long, branching, fronds that make for a beautiful addition to any display tank or refugium in need of a splash of color.
  3. Removes Excess Nutrients
    This species of macroalgae grows quickly and cleans your tank by consuming excess Nitrates & Phosphates for easy nutrient export. Balance your nutrient levels and watch your in-tank ecosystem thrive!

Manufacturer information

We think the best way to inspire people to protect our oceans is to help them observe, understand and learn from the magnificent creatures that inhabit them. That’s why at Algaebarn we produce premium aquacultured marine organisms that are sustainable and eco-friendly. By providing quality live foods backed by scientific research, we aspire to improve the general health and longevity of ornamental fish. One day we hope to see all marine aquariums filled entirely with aquacultured organisms, thus reducing our hobby’s impact on natural marine environments. The best way to make that vision a reality is to start with the building blocks of all marine ecosystems; Zooplankton and Phytoplankton. We grow all of our premium Copepods and Phytoplankton at the base of the Rocky Mountains in our state of the art 2,000sqft aquaculture facility. As hobbyists ourselves we understand the importance of knowing what goes into your aquarium. That’s why we run all of our water through a twelve stage RODI system before mixing in InstantOcean synthetic sea salt. There are no fish or copper parts anywhere in our facility so you never have to worry about introducing anything unwanted into your aquarium. We only sell premium live Copepods & nutritious Phytoplankton with no harmful chemicals or preservatives.

Created a Mess

I got this to help control my nutrients since I don't have a refugium. It did help get my nitrates under control but it is pretty fragile and little branches were breaking off and blowing all over. It took forever to find and remove all of the pieces.

Pros: none

Cons: dies fast

I decided to add red ogo to my refugium because I read that tangs will eat red ogo. I originally bought 8 ounces about 5 weeks ago. The color was more of a burgundy and not the bright red shown in the picture. It was a lot less than I thought, so I bought another 16 ounces. This batch came almost greenish brown and not red or burgundy. About a week later, I started noticing less and less ogo in my refugium. It's been about 2 weeks since the I added the 16 ounces and the red ogo is almost completely gone from my refugium. I will never buy this again.
