I am using a 2.5gal glass aquarium. I removed the plastic upper cover (breaking off a small piece in the process) and removed excess silicone. I will probably leave the top on and retrofit a lid that I can seal in place and have a hole in the center to access the inside.
Since I do not have ready access to ytong, I am using grout. After measuring the inside length of the tank, I built a frame and poured approximately 1.5” of unsanded grout. It took about 2 days to set up.


I removed the frame so it could finish curing.

Like the chambers in the videos, I am making seperate nests so I can slowly add more space as I need it. I have no colonies that are big enough to fill either of these sides. I am going to make 2 side nests that will consist of only 1 or 2 chambers that can be used as a psuedo-founding nest.

Just about finished with the front. This piece will be fitted and siliconed to the inside of the aquarium.
