On the 4 day black-out, I've had mixed results reported on this, but
mostly negative. I assume that for it to be effective, there must be
some other condition in the tank, (perhaps they are approaching some
growth constraint?). Let us know how it worked for you. I also found
water changes ineffective. Had good results reported from using a
phosphate pillow though.

You obviously haven't ever had a bloom of green water algae then, have
you ?
You can do a 90% water change - which I have, and 3 days later it's pea
soup
green again. Especially if you're running high lighting for a planted
tank.
I suspect you could even take the fish out and do a 100% water change,
and
the problem would still not go away, still the algal cells would just
settle
to the bottom in the gravel, and then resuspend when you filled it back
up.
The only way a water change could help would be if you also disinfected
everything in between - a complete tear down. Disinfect the gravel,
disinfect and scrub the inside of the tank, chlorine-dip all the plants
and
driftwood and anything else in the tank. This is something I want to
avoid.
Since having the green water algae bloom, I've done up to 80% water
changes
every 3 days, just to keep it from looking like crap. I'm currently
trying
the "total darkness" method I read about on the Kribs. Theoretically,
4
days or so of total darkness kills the primitive single celled algae
completely while the fish and the higher plants do not suffer. Well,
at
least the plants do not suffer to the point of dying.
I'm crossing my fingers .....

IMHO, a water change or many would be better.

Does anyone have experience treating "green water algae"

with
barley straw extract ? What were your conclusions ? Did it work or
not
work ?
Also, does it actually *kill* the algae ? Or does it just clarify
the
water
in some other way ? I have a 55gal tank and the bottle I was
looking at
online at www.thatfishplace.com says it treats 2,500gals. So that's
making
me think now that I have the infestation, I'll have to treat it
forever
and
ever.
If barley straw extract ISN'T the best way to deal with green water
algae,
what is ?
