Can i use macroalgae in a small reef tank / nano-tank ?

Absolutely :) We recommend for smaller reef tanks / Nano-Tanks because of the limited space marine macroalgae species which are non-invasive and slower growing.

Especially a lot of red marine macroalgae species are perfect for those conditions.

Please have a look at our section for Nano-Tanks, where we added all the macroalgae species which will do just great in a smaller aquarium.
