I have some algae that appears to be BGA on some plants and it's releasing all sorts of oxygen bubbles from the leaves that it's growing on. From what I understand it's actually bacteria that can go photosynthesis. It's only on the old stunted parts of my Rotala before I got my co2 and higher light running. The new growth on the Rotala is now pinkish/red and looking great and no algae is able to compete with the new parts of it.
So my question is...do I need to dip the plants and replant or just wait until the new growth on the Rotala tops get big enough to cut off and replant and just toss out the old growth part of the stem that's being taken to school by this algae?
