Benefits of marine macro algae in the marine aquarium

Enrich your marine aquarium, reef tank or seahorse tank with stunning and colourful looking macroalgae and be amazed how live algae can transform the look of your tank, bringing the marine aquarium hobby to a completely new level of enjoyment.

Just a few reasons, why macroalgae are a great addition to the marine aquarium:

  • Ability to suppress unwanted micro algae, like green hair algae etc.

  • Reducing the nitrate and phosphate level in the tank

  • 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

  • A more natural look of the marine aquarium to enjoy

When it comes to marine macroalgae often the first algae named are the green algae species like Caulerpa or Chaetomorpha ( Chaeto ) as they are fast growing and commonly available.

Chaetomorpha ( Chaeto ) is a great macro alga for the refugium as a nutrient export choice, but we would rather not recommend it for your aquarium display as it isn't that nice looking.

Various Caulerpa algae species are a great choice for a nutrient remover algae in the refugium, and as well good looking for the tank display too, adding fast a more natural look.

Especially the Caulerpa Taxifolia, Caulerpa Racemosa and Caulerpa Prolifera species look very beautiful. As they are more invasive and might go sexual ( read about this in the care facts for Caulerpa macroalgae ) they will need more attention than non-invasive algae species.

The red, green and brown algae species in our non-invasive macroalgae section will be a good choice for the most marine aquarium, as for the Nano Tank, Reef Tank or Fish only Tank Display. Especially for Seahorses aquarium, we recommend them, as they provide extra hold fast and more comfortable for the seahorses.

These live algae will often grow slower, especially in comparison to the various Caulerpa macroalgae species, and are therefore not the first choice when it comes to a fast nutrient export, but they look with their different colours and shapes just stunning and might compete regards its beauty with the one or the other coral in a reef tank.

If you don't already have live macro algae in your tank, perhaps the pictures will convince you to enrich your tank with a more natural look and happier fishes and seahorses.

Our goal is that you will like your algae so much that you won't be able to resist coming back over and over again to purchase more! :)

We are looking forward to your feedback.

What means "Regrowing"?

When a macro algae species sells well we have sometimes to take it out of the sale as it will need time to regrow again.

The time for this will vary, as some macro algae species will grow very slow, whilst other - especially various  Caulerpa marine macro algae species grow quite fast.
