How is your algae growing going?
Extremely slow....I think some strings start to grow on the lava rocks. I still have the feeling that the tank is more or less cycled as there seem to be some bio film on the stones.....
I think i’ll wait two more weeks and ask the guy where i’ll buy my shrimps, to provide me with enough water to fill my tank not be sure there are enough bacteria in the water, as a water change will be necessary anyhow before introducing them.
