Bright green algae that comes off easily? That sounds like BGA,
cyanobacteria or slime algae.... whatever you want to call it.

I've had a fight with all sorts of algae for the last several years
(6yrs?). That BGA sure makes a mess out of things. I have tried every
remedy I know of or heard of. FOR ME it has come down to two things,
actually three. You can tear the tank down and restart and hope for
the best...... use some death in a bottle available at any local
*mart, like my buddy does (and seems to work)...... or change your
lighting. I've changed mine till I was tired of fooling with it.
Different color temps, varying duration, intensity, etc.... etc.... I
finally bought a timer with multiple setpoint for purely selfish
reason. So I could see my tank lit before and after work and still
only get 10-12 hours of light. Now it runs from 7am to 11am and from
5pm to 10pm. That's nine hours of light. But, what the!? No algae.
ever. Go figure.

Take that for what it's worth.

There is another alternative, accept the algae as a natural part of
the aquatic environment. One of my tanks has been slowly growing red
amoeba along the water/gravel line. I worried for the first year, but
seeing no problem caused by them, I have decided, they too, are a
natural part of the system. Snails too.

We all fight for some idealized perfection without considering
accepting what is natural.
