How do you avoid getting algae in your aquarium? I currently have a 75 gallon and will be moving my fish to a 120 gallon as soon as it finishes cycling.
I have that black hair algae or BBA in my 75 gallon. I had bought a plant at my
lfs that had a little bit of black stuff on the end of the leaf - that's how it got into my tank. It's all over everything right now. I periodically take everything out, my husband pressure washes the furniture and I scrub the walls, tubing, cut back the plants where it is growing. It's just awful stuff.
So when I move my fish into the new tank, I do not want to bring any of the algae with them. So I am only moving the fish and nothing else from that tank.
Anyway, once I have my babies moved into the new tank, how do I keep algae out.
I know that these things will encourage algae:
1. Overfeeding the fish.
2. More than 6 hours of light in the tank.
3. So having the tank right at a window is not a good idea.
4. Poor water quality will contribute to algae.
What else?
I've heard that running
co2 into the tank will discourage algae, but this is a tricky thing and I really don't want to do it. If you have too much
co2, I've read that it can encourage algae. And I just don't want a pressurized
co2 tank under my aquarium. Boom

Is there anything else I can do to prevent algae in my aquarium? I'd really appreciate hearing from you all what works for you.
