Benefits

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.

Add color & texture

Red Ogo has a 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.

Remove excess nutrients

Red Ogo 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!

Description

Red Ogo Gracilaria Live Macroalgae

The Red Ogo (Gracilaria Parvispora) plant 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. Red Ogo Gracilaria is a fast growing and hardy macroalgae when kept under proper conditions. It is also great for nutrient export in saltwater aquarium systems. Additionally, it is prized by many herbivorous fish keepers (especially tangs) as a healthy live seaweed food. Pro Tip: Red Ogo Gracilaria can be grown out in the refugium and new growth can be trimmed and fed to herbivorous fish as a tasty treat.

*Please note that while we go to great lengths to treat, quarantine and remove any unwanted parasites, hitchhikers, and other organisms from our red ogo macroalgae we do not guarantee that this item is completely and totally free of anything unwanted. This is because sometimes spores, eggs, etc can remain viable but not visible, despite our strict quarantine procedure. We strive to have the cleanest and highest quality macroalgae on the market. AlgaeBarn always recommends that you properly quarantine anything new before adding it to your tank. All of our macroalgae, and everything else we sell comes with a 100% Alive On Arrival Guarantee.

Excellent Quality and Fast Shipping!

I ordered Chaeto and Red Ogo from AlgaeBarn, and both arrived fresh, vibrant, and super healthy. The packaging was top-notch, and everything was clearly labeled.

Seems healthy, nice color.

Appears to be growing. A lot of loose pieces, but I’ve never had this variety before , so maybe that’s normal.

Red Ogo

The other macro algae i have got from y'all was great the Red logo and turned white and is slowly falling apart

Hi, thank you for your review. It sounds like something else might be going on if one is thriving and the other is turning white and falling apart. Our team is well versed in all things macroalgae, and would love to help you trouble shoot and see if there isn't something we can do to keep that macro growing strong! You can email us at [email protected] We look forward to hearing from you soon!

DOA, or practically dead

Tried to get it to come back but no good. Also tried contacting support and no response.

Hi there,

Thank you for taking the time to leave a review about your experience with Red Ogo. We are sorry to hear that it arrived DOA and that you were unable to revive it. We take the quality of our products seriously and would like to make things right for you.

After checking our records, we don't see any previous contact from you regarding this issue. It's possible that you may have used a different email or name when reaching out to us. In any case, we would love to assist you further if you could reply to the email that was just sent to you.

We appreciate your feedback and hope to have the opportunity to make things right for you.
