Aquarium Setup using Walstad Method. - 7-Weeks

7-Weeks back, I has set up a Walstad Aquarium. 7-weeks had passed by and now the water had started looking yellowish. There were 2-major reasons for this yellowish water.


1. I had introduced, a blob of live tubifex worms in the tank. I just left them  in a plate inside the aquarium. As the worms die, a thin layer of biofilm is created, floating at the water surface. 


2. Introduced 4-pairs of Neon Tetra and 3 Pairs of Butterfly Guppies. This created a sudden increase in bio-waste, resulting in sudden burst in Ammonia and Nitrite and other water nutrients. This builds a classic case for Algae, which you can see on  Amazon Sword and Anubias.  


I immediately did a 20% water change and here are the results.

Finally the tall grass has shown some growth. A new Leaf has sprouted and one of the old leaf has grown tall and is almost touching the water level in the above pic. There are now in all 7 Leafs in this grass plant. I need to find the name of this plant. :)

Notice the Brown Algae, has started spreading on the Leaves. I am bringing a Sucker Fish, I hope it will take care of this Algae.
