I have a tiny bit of duckweed. Everyone hates this stuff and say it completely takes over their tanks but I find it absolutely beautiful and can’t wait for my duckweed to grow over my tanks for a more naturalistic look 😍
@Jayden Recktenwalt I actually have the duckweed in my 10g tank. And because I don’t have an airstone there I don’t let the duckweed cover more than 2/3 of the surface so that there can be oxygen exchange still. But I have a lot of fish in each tank that’s why I watch it carefully. Also, I thought duckweed gave oxygen because I assumed all plants consume CO2 and exhale O2
How much duckweed does it take on a per fish per day sort of basis or some other measure that would tell us how much surface area we need to be using to feed the tilapia or whatever with just duckweed? Thanks.
By introducing air into the water, he also introduces CO2 and other gases. You need Oxygen for the bacteria that break down nutrients into usable Nitrite/Nitrate which helps duckweed grow. If you don't do this, it will choke the water surface which essentially means the bacteria below will die off and the Duckweed follows before the cycle repeats. Which is not ideal if your aim is to harvest the duckweed. You want a healthy plant that can be processed into food for other fish or shrimp. Edit; If you ever seen Mass Death of fish stories where a large quantity of fish die for no particular reason. That is due the oxygen in the water vanishing. The bacteria is the culprit for all the oxygen vanishing since they use large amounts to decompose organic matter.
Arianna Marmolejos Nails are for construction, so I don't know why you would do that... also, duckweed is a freshwater plant so I don't think sea creatures belong in freshwater.
