fresh out, salty in

A freshwater nano cube's rebirth as a nano reef.

Step 1:
I removed all the freshwater stuff and cleaned the cube

Step 2:
I cutted the undergravel plates into the right size

Step 3: I put the plates in

Step 4: I removed the freshwater energy
 saving lamp and replaced it with a marine lamp

Step 5: added the filter to the undergravel plates

Step 6: added a thin  layer of filter floss to prevent
the gravel from falling through the plates

Step 7: added used gravel from my
other marine cube to bring all the useful bacterias in

Step 8: add the rocks, used water out of
my other marine cube and macro algae

The final result with just a few soft corals.
If it runs stable I will add some more corals in a few weeks.
