A quick update on office aquarium. Plants are growing like crazy. Every one of them looks healthy. Specially the floating duckweed and amazon frogbit. Of the 6 shrimp, at least one died. It's difficult to find them, so I am not sure how many are still alive, as far as I can tell, they have not bred. Snails have, lots of tiny snails and eggs all over. Also for the first time, I see tiny crustaceans in one of my aquariums. I need to get a good magnifying glass to figure out exactly which but it was very cool to see them darting around. I removed the filter media from the water filter, so it is now just used to provide water movement.
The biggest problem has been brown water. I have had to twice change about 60% of the water because it becomes so brown that almost no light reaches the bottom. Oxygen also seems to be a problem in this state and I see all the shrimp sitting on the surface of the water. I have also had H2S bubbles from substrate, but they seem few enough to not be worried about.
A list of plants in, before I forget them:
Here are couple of pictures.
