Introduction to Marine Macroalgae Part I

Macroalgae, or sometimes so called seaweed, seems to have become within the last years more and more popular amongst marine aquarium hobbyists.

Previously macroalgae was often used specifically to provide a natural way to export the nutrients in the aquarium water, which means that the algae will grow by using compounds like nitrate, phosphate, ammonium and some heavy metals in the tank water.

During this photosynthesis process it uses carbon dioxide too and turns this into additional oxygen for the aquarium inhabitants.

As well it will help to raise the pH level in the tank and increase the tank carbonate buffer capacity, which means are more stable alkalinity level.

In addition it is often used to provide additional hiding spaces for copepods and rotifers.

Nowadays thanks to the variety of available macroalgae species, macroalgae can still fulfill these very important functions but they add a very important benefit too . . .

. . . a beautiful and more natural looking tank.

Very important is of course the right choice
of macroalgae species.

As there are invasive and non-invasive algae species available, it is recommended to get all the information you need about the macroalgae in mind before adding it to your marine tank.
I guess no one likes to realize having chosen the wrong macroalgae for the tank, maybe overgrowing the whole tank or the corals.

My aim is to provide you all the information you need to choose the right macroalgae for your tank and to keep them successfully and thriving.

You might wonder why I actually recommend to have macroalgae in the tank, while so many people seem to try to get rid of algae in their tank using chemical or mechanical nitrate and phosphate remover, to reach a phosphate/nitrate level of 0.

Well, the truth lies in the difference.

Microalgae on the one side, like phytoplankton, provide a important food base in the open sea. They are mostly one-cell algae species.

Especially microalgae species like diatoms (Bacillariophyta), green hair algae (Chlorophyta) and the dinoflagellates (Dinophyta) are the most problematic microalgae you will come across in the marine tank hobby, as they can become a serious problem in the tank.

So called Macroalgae on the other side, are easy explained algae which you can see with your naked eye and contain mostly many cells.

  • Ability to suppress unwanted microalgae, like green hair algae etc.
  • Reducing the nitrate and phosphate level in the marine aquarium
  • Providing shelter for small fishes, copepods and rotifers
  • Natural food source for critters and fishes to keep them happy and healthy especially Tang fishes need a good portion of daily algae to stay fit and healthy
  • More natural look of the marine aquarium to enjoy

BTW: Algae is already the plural for these marine plants, and in singular it is called Alga 🙂

I Love Macroalgae

Hello and Welcome to my Livealgae Blog.
I love marine #macroalgae and as there are so many varieties, which are very different to care for, I thought it is the right time now to start this blog.  Sure there are a lot of explanations about macroalgae out there, but unfortunately often just about the basic care facts. But there are so many more things to know about, that they will do best in your tank and not cause any problems with your corals or fishes.
I keep macroalgae since 14 years now, and I lost some over the years, but most of them do luckily very well in my three tanks. So I will give you for each algae species I write about, beside of the basic care fact, my individual experience and recommendation.
Let’s share the passion and the knowledge, and maybe some algae too . And if you are not already macroalgae addicted like me…
Perhaps this blog will persuade you into the beautiful world of marine macroalgae…
My passion for marine macroalgae was born 14 years ago, when I got a nice Yellow Tang. Surely a very common fish, but a beautiful one with a sweet personality.
Unfortunately after a while I noticed that he became more and more aggressive towards the other fishes when it came to food.
So I started to give him dried Nori Algae to keep him calm, which worked quite well. He loved it, and always tried to protect it from others.
Looking for a more natural and permanent food solution for him the journey started.
And here I am now !

The beautiful diversity of marine macroalgae caught me and I collected so far around 20 different colorful and beautiful looking varieties.
To share the passion with you, and to exchange knowledge about marine macroalgae I am looking forward to hear from you.
