Blue Green Algae causes
Hi! I set up my first planted tank three months ago. It is a 29 gallon with
an Eclipse three hood. I have a gravel mixed with laterite substrate.
Things went fine for a month or so. Then Blue green algae smothered
everything. I nuked it with erythromycin and thankfully it died in big
chunks. It has been a week and a half since the 50 percent water change that
I did to get most of the dead algae. So far no BGA but some kind of white
fluffy stuff growing on a piece of wood that has always been there and a very
little bit of green dot algae. These do not worry me but I do not want the
BGA back. I wonder what caused it in the first place. I used all the
tablets and liquid recommended on packages when I first started. Did I over
fertilize? I thought that it might be caused by an excess of iron or
phosphates. I put some water lettuce in to try to sop up extra nutrients.
It is growing quickly, i.e. put out three babies in a week. Now I am afraid
to fertilize, what should I do? I also want to do this plant thing without
C02 because I don't have the money for an expensive set up and I don't
understand how it works very well. Can I grow plants without C02 injection?
Also in an unrelated question, what do you do to grow those baby Java ferns
that sprout from spores on the leaves? I guess that is all for now. Thanks,
