 Re: Freshwater Refugium?
Hi, I agree with the above, there are some sewage plants that are prototyping the effectiveness of duckweed as a refrigium as well. So your idea is valid it seems since I doubt your tanks would ever get as bad as sewage ! If you're not concerned with looks, duckweed is the way to go. It sucks up nutrients super fast.
I put it in all the tanks that I have algae issues with and it very quickly stops algae growth. |
