Newly bought emersed Java Fern introduced to tank. Need to inject CO2 and add Excel?
For the past 2 weeks, my tank was taken over by BBA. I tried to clean it up by spraying Excel directly onto the java fern leaves but only managed to burn the leaves and turned them brown. I cut off the dead leaves, leaving only the rhizome but still the algae took over.
So I removed the driftwood and cleaned it up, gravel vacuumed the tank, cleaned the algae and bought new java ferns for the tank. I bought them from a LFS and they were just in a plastic bag attached to a piece of wood.
Now that they have been placed in my tank, as my tank has a pressurized CO2 setup, should I still inject CO2 and add Excel to the tank so that the BBA does not take over again?
Or should I just let the java fern be, without CO2 and Excel?
How long will they take to acclimatise to being submersed?
