Newly bought emersed Java Fern introduced to tank. Need to inject CO2 and add Excel?

Hi guys,

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?

After using Excell my Java died back and the next batch of leaves were mutated. i believe Chad had the same observation with his.

I don't use Excell at all now. I use H2O2 for algae if needed

There is a difference between spraying it on the leaves of the plant, and just adding it to the water as it was designed for. It was never designed or marketed as an algae treatment, hobbyists came up with that on their own.

I have never seen any difference in the growth form of Java fern emersed or submersed. It is a slow growing plant that pretty much stays the same either above water or below water. Adding actual C02, not Excel, will speed up growth underwater to some extent. It doesn't need to "acclimate".

Like Dogfish, I too have had issue with glut and java fern. If you are getting bba, more co2 and less light are the key to preventing it. Using it AS DIRECTED it killed java fern for me.

Emmersed it grows exponentially faster for me. New leaves every few days. No algae worries either. It converts pretty easily to submersed growth. Glut helps many plants but I don't recommend it's use as a prophylactic algaecide. Reducing light and/or increasing co2 is really the key.

I use it for staghorn on the sides of the java fern leaves but I'm to afraid to try it on the rhizome. I don't want to demolish these ferns.
