I almost never say "algae". It is either green water (Phytoplankton) or moss
(Plecostomus food) that clings to glass or plants. Green water is more
danjerous, because given sufficient fertilizer in my water, it can grow
exponentially, and when lights go out, decay just as fast. When lights go
out, it consumes oxygen, and with enough density, it makes fish surface. So,
I prefer moss, which is easy to remove from a filter or glass, or easy to
remove with a siphon as a component of silt from Plecos. When other people
say algae, I often ask them to clarify: Moss or green water?

Hmmm, ponders usually ask, pea soup or sweater/side algae? String or
Blanket weed? Slime or snot algae? When one is dealing with the sun and not
just light bulbs, algae really can take a turn for the worst.... or better.
;-) I have "real" moss growing on my waterfall, sphagnum moss, a great
filter, stays green all winter even. ~ jan
