THe Nano Cube has been sitting and cycling for some time. I have added some livestock into it already and have been petrified that I will kill everything in there with my over enthusiasm. I have about four Rocket Snails and a couple of “Nemo’s”. The snails are nice because they keep the algae to a minimum and the fish are scredy cats, but are slowly starting to eat.
To recap, I have been cycling the Nano cube for about three weeks now, I have about 8 pounds of live rock, about an inch and a half of crushed coral substrate, and the water parameters are holding up nicely (too nicely in my opinion). I check the water once a week when I do a small partial water change and Nitrate and Nitrite seem to be close to or at 0 ppm. Ammonia rises and falls, but stays within the lowest place in the chart. I did follow the advice of a commenter and start using RO water exclusively for my water changes and have been happy with the results.
The more time I spend with the Nano Cube, the more I dislike the design. The filters are placed in the back which makes filter cleaning quite a chore and I end up putting a lot of the detritus from the sponges back into the water. I have to be really careful to remove the filter and put it back. On one such water change, I stirred up so much stuff that I thought I was going to stifle the poor Clown fish. I wish the nano had better access to the filter compartment and had more places to put inlet tubes and wires into it.
I will let it cycle for another week before adding anymore livestock, but the next order of purchase will be a shrimp of some kind. I am worried that crustaceans are really susceptible to water parameter changes, but the uneaten food in the tank is a problem. The clowns are very young and they only will eat frozen food. In addition, they are very very jumpy and scared and the food ends up everywhere. I even cut the smallest frozen food cubes into six or seven smaller peices to keep uneaten food to a minimum. I just think a nice hermit crab or peppermint shrimp would love the stuff floating around.
I would like to see some corraline algea before I buy any corals or such but I see a couple of very young feather dusters beginning to take shape. I hope there are many more to come. The harder I work on keeping this Nano Cube reef, the more excited I get about it and the more fun it becomes!
