Caulerpa Racemosa Cylindracea Marine Macroalgae for the Planted Reef Display Tank & Refugium/Sump.
Live Algae UK - Clean Marine Macro Algae from Fish&Copper free tanks since 2014. Sustainable grown in the UK.

This Caulerpa macroalgae species loves the light, as the more you provide as faster it will grow.

Herbivore fishes are sometimes interested in the roots but not much in the algae structure by itself.

As Caulerpa Racemosa  will attach itself to rock etc. we recommend not to place this marine algae too close to your main rock, unlike you like to have it there. It needs some trimming and attention as it is fast growing. Great to keep in the sump as well.

Caulerpa Case
Some Caulerpa macroalgae species might go sexual, which means that it releases gametes and tissue into the aquarium water. Although this said, we never had in 14 years any problem with this algae species, and it was one of the first macroalgae we got. One thing to avoid this is good light and to remove pale turning parts of it.

Whitish parts of Caulerpa Racemosa should be removed as they are decomposing.

Like for most marine macro algae a higher level of Nitrate and Phosphate, in addition to the supplement of Iron, Magnesium and Trace elements will improve the growth of this algae.

This macroalgae can be either placed in the Refugium or in the marine Display Tank where it would need an enclosed space to avoid it overgrowing the reef tank.

Please note
Our macroalgae are from fish free macro algae tanks, although we use pictures for demonstration purposes only which will include fishes, seahorses and or corals. 
We do our best to quarantine, treat and remove any unwanted hitchhikers, parasites etc from our macro algae but we can not guarantee that the algae are completely free of anything unwanted, not limited to Copepods, Rotifers etc. This is simply because that sometimes eggs, spores, etc can remain viable but not visible and hitchhikers can still stay hidden, especially in dense algae structures, despite our strict quarantine efforts. 

All macro algae will be thoroughly dipped in a professional solution to deactivate hitchhikers as good as possible before posting. If you don't want this, please send us a message together with your order.

We highly recommend nonetheless that you properly quarantine anything new before adding it to your marine tank.

We aim to offer you the healthiest and best quality macro algae on the market, therefore, all of our macro algae comes with a 100% Satisfaction Guarantee.

questions Mark on 30/10/2018

How would you say that macro algae rated in terms of hardiness compared to prolifera?


Hi Mark and Thank you for your question.

This macro algae is quite hardy but it needs always enough nitrate and phosphate, as it grows much faster it starves much faster :)

Have in mind it that this alga grows almost double as fast as Caulerpa Prolifera. But it is easy to see when something is wrong as in this case the whole algae collapse and turns mushy, still quite easy to remove when this happened. Talking about going sexual and polluting the water we had never a problem with that.

Please bear in mind that any use of chemical Nitrate or Phosphate remover would harm this alga very easy.

questions Mark on 30/10/2018

That's good to know . As for chemical no3/po4 reduction starving the algae there shouldn't be an issue there as I just run a fuge and efficient skimmer as sole nutrient export . Are refugiums consisting of mixed caulerpa species viable ?


Yes that normally works very well, as you might mix it with medium fast growers and fast growing macro algae species.

We just received a few days ago a very nice feedback from a customer about our fast-growing macro algae pack which has 4 different species in it btw. This helped him very well in lowering the Nitrate & Phosphate levels.

Kind regards

questions Mark on 30/10/2018

Hello again Manfred . I have looked at the various caulerpa species available on your site and would like to ask for a bit more advice . My refugium is 46cm x 47cm with water depth of 26cm, used as primary method of nutrient export . It is lit by a 300w 6400k cfl grow light . I am looking at potentially 1 portion each of Prolifera , Racemosa and Taxifola . Would a refugium that size support 3 species comfortably without too many issues ? If not based on the refugium size and goals, which species would you recommend? How much rock would you suggest for attachment and growth for the given size if refugium? On the subject of attachment , does it have to be rock ? Are there any alternatives worth looking at? Thanks


Hi Mark.

The size of your sump will provide a good size for those three algae species.
I would recommend adding a divider between the Caulerpa Racemosa and the other two Caulerpa species though, as it grows faster and might overgrow them, taking the light.

The Caulerpa Racemosa can eventually attach itself to the glass but, but needs to stay close to it for a while. 

The Caulerpa Taxifolia and Prolifera won't do this normally, so for them I would recommend just to add a few small pieces of rock, so they can attach and stay at the bottom of your sump, which isn't necessary for the Caulerpa Racemosa, this can just stay in your sump, even floating would be alright as long as it gets enough light.

Regards your light I wonder if you have thought about to change this in the future, as you should be good even with a more energy efficient LED Light? For example with a 300W LED Light ( maybe using the brand "Mars Hydro" Full Spectrum ) it should provide enough light too, while effectively just using 150 watts.
