Marimo tank mess
I am the new owner of a family of marimos. They live in a two-gallon tear-drop shaped bowl with 5 pounds of washed aquarium gravel and a small piece of Mopani wood on my dinette table.
All was well until I added an Argentine sword plant from a pet shop. That introduced some bacteria that have made themselves at home, covering everything with smelly yuck.
I removed the plant to a plastic container where it can grow new water leaves. I thought I could wait it out until more civilized bacteria took over in the marimo bowl, but things are not looking good. Changing most of the water several time a week isn't doing the trick.
I need to know how to rescue my moss balls and stabilize the tank. I am considering moving the moss balls to a holding container separate from the plant and boiling the heck out of the gravel and wood. I hear there are sources of "tame" bacterial that I could add to the tank and the two containers until things clear up.
Any helpful suggestions would be appreciated.
