Green Grape Algae, Caulerpa Racemosa, Aquacultured Refugium Macroalgae

Picture of Grape Caulerpa, Caulerpa Racemosa, Aquacultured


Our Clean Macroalgae is aquacultured in large vats not connected to any fish system to avoid possible parasite or bacteria contamination. You can place our macroalgae directly in your tank without worry.

Description: Caulerpa Racemosa also known as green grape algae is an excellent way to lower nitrates and phosphates in the aquarium. By placing in the tank, sump or refugium, the macroalgae absorbs phosphates and nitrates from the water. By removing portions of the Green Grape Algae from the tank, it is effectively lowering the excess nutrients in the saltwater the caulerpa racemosa absorbed while growing. Caulerpa racemosa is unique in that it has perfectly round individual clusters, resembling grapes on a vine.

If you are not using algae to eliminate high nutrient levels of nitrates, phosphates and other toxins you are missing out. Simply put all these nutrients, ammonia, nitrites, nitrates and phosphates are used by your algae as a fertilizer to grow and once removed from the water the levels of the toxins goes way down. In fact in many fish only aquariums, keeping algae will allow the aquarist to almost eliminate the need for water changes altogether.

This is a warm water algae species we aquaculture that won’t shock from typical saltwater aquarium temperatures of 76 – 84 degrees. Found in sub-tropical Florida, as well as throughout the Caribbean. Used responsibly, Caulerpa racemosa can be ornamental additions to a display tank or help control the nutrient load of a large reef tank. Quite popular with aquarist's, many grow it in their refugium, sump or in the aquarium itself. Although illegal in the state of California, Caulerpa racemosa grows well, and needs pruning every few weeks. As you can see, it has a distinctive look you can quickly recognize and some refer to it as Grape Caulerpa. To keep from going sexual (and disintegrating) the refugium or sump light needs to be kept on 24 hours a day over this plant.

Difficulty to Grow:Easy

Reef Safe:Yes

Lighting Requirements:Provide 75 to 100 watts of 5100K to 6700K floodlight lighting or equivalent fluorescent lighting to thrive. It is important to promote a good growth rate, as the harvested caulerpa algae is what removes the nutrients from the aquarium ecosystem. Faster algae growth will allow for more frequent harvesting, which will in turn increase the filtration benefit of the Caulerpa racemosa Algae.

Waterflow:While Caulerpa racemosa is easy to grow in most conditions, it will be much more efficient at nutrient export if provided ideal conditions. Ideally it should be grown in the sump or refugium where it will have low water currents and can be provided plenty of light.

Water Parameters:76-84° F, dKH 8-12, pH 8.1-8.4, sg 1.023-1.026

Supplements: Magnesium, Trace Elements, Iron

Care Info.. Float the unopened bag of your macroalgae in the aquarium for 30 minutes to 1 hour to allow the temperatures to equalize. Then place the algae in your tank, sump, or refugium. Trim back your algae periodically to directly remove the absorbed toxins from your water. You may also keep it as food for your herbivore fish.

*Guarantee Restriction: All of our livestock are guaranteed. However for one or more of these species, they may be marked with a guarantee restriction. If it does, it means the specific animal may not handle stress from environmental conditions well. These stresses can include poor water quality, harassment from tank mates or confined aquarium conditions. When stressed, these species can lose the ability to ward off infection and disease. Other species may be listed as Restricted because they have such specialized feeding requirements that is difficult recreate in a aquarium and may succumb to malnutrition.
