Non-Invasive Macroalgae Species

Welcome to the beautiful world of marine macro algae for the Display Tank & Refugium
Your 1st choice for Sustainable Grown Macroalgae Species in the UK since 2014

The following macro algae species are known as non-invasive, which means that they won't attach themselves to your rock work etc. and without the possible risk of overgrowing the whole aquarium tank.

Thus they are the ideal algae plants for the Marine Aquarium Display Tank, either a Reef Aquarium or a Seahorse Tank.

Usually, these algae species are very easy to keep in the aquarium and the care level is much lower than for example with some Caulerpa macroalgae species. But at the same time, they grow much slower than some invasive Caulerpa macroalgae species for example.

If you wish to keep them in place, you might need to superglue or rubberband it to a piece of rock for example.

All the algae we sell are from our special Algae Tanks setups which are kept without any fishes for a disease-free and premium quality. This said, they might come with hitchhikers not limited to Copepods and Rotifers, as those beneficial critters love the protected environment of our planted marine tanks.

Marine macroalgae will provide you still all the other great benefits, which we explain more in the FAQ part.

We hope you enjoy our beautiful marine macroalgae collection and if you have any questions don't hesitate to contact us.

How to achieve better macroalgae growth?

Macroalgae don't need a lot to grow, just good lighting and enough nutrients.

Should you already have good lighting for your macroalgae but the growth is not as it should be, maybe there are some nutrients missing in your aquarium water which it need to grow?
