Caulerpa macroalgae species are widely available, as they grow often very fast and are therefore properly maintained a great choice for the nutrients export from the tank water ( read more about in our introduction ) plus they add a lot of other beneficial advantages to the marine aquarium.
There are a lot of rumours going on about the danger of using Caulerpa macro algae species in the marine aquarium.
Therefore it is very important to know that there are a lot of very different species available which belong to the Caulerpa family and some of them are quite hardy macroalgae species, like Caulerpa Prolifera, which means that we haven't experienced any problem at all of polluting the water environment or causing any other problems with those algae species.
But there are some Caulerpa species, which will need a bit more care to avoid any issues, as some Caulerpa species might go sexual, which means that it releases gametes and tissue into the aquarium water.
One of the main reasons for this is the fast change of the water quality, like a sudden change of the Salinity, PH, Alkalinity and Temperature and of course a different lighting, eg lower lumen provided than before, or faulty light units.
Therefore it is necessary to remove pale turning parts of the macro algae as soon as possible out of the marine aquarium and to keep a stable marine water environment plus provide good lighting.
If it does go sexual you might end up with new growth of the macro algae all over your tank, which will be harder to control and in very rare cases, especially when a lot of Caulerpa species have been kept in the tank, it might pollute the marine water that much, that a larger water exchange might become necessary.
Although this said, as we always keep a close eye on our macro algae, we personally never had in 15 years any problem with this algae species, and it was one of the first macroalgae we got.
