Mystery algae photos
So did I . . . it's never off except when I'm doing maintenance.
BTW, I checked with several local pond stores that do maintenance contracts:
they've seen this stuff before, and figure it's just a cyclical thing algae
goes through for "renewal". It's never caused a problem, other than the need
for extra cleaning. For some reason or other, it cleared up over the
weekend, and other than a funky looking liner (growing new algea, though),
the water is crystal clear again.
Go figure!!!

Wow, too bad about the big ones. We have the pump on 24/7 and have never
lost fish to O2 issues.

Mine was very bad; I came out one morning, and my largest fish were
dead.
That's classic oxygen deprivation. I added a large, 4-airstone setup to
my
pond, and the fish now have adequate oxygen, regardless of the water
temp
or
what the plants want to do. My pond circulates 2.5 times per hour, and I
NEVER shut it off (except for maintenance). You're right UG-LY! stuff.
And
I
noticed the same thing: it appeared to break loose from the bottom and
sides - there were different colored patches on the liner that seemed to
be
the origin. They rose to the surface when the water heated during the
day,
and sunk back down at night when the water cooled a bit. But I was
heavily
planted last year; between the plants and the algae doing it's thing
with
the O2 during the night, I lost fish. Big ones. 18 inchers. Then I put
in
the airstone.
I want to know what it is. More importantly, I want to know how to get
it
the (expletive deleted) out of my pond!

We have had the black clump day algae for four years. It sinks at
night.
No fish loss from it thus far...but then we have our circulation on
24/7.
Jim scoops it off with a net when it gets to be too ugly. That
reduces
it
but does not remove it. It seems to form on the bottom and then break
free
to rise up...or maybe it it just falls to the bottom and then rises
up.
Ugly, but apparently not harmful.

ACK! Any chance it will go away by itself? Like some of the others,
I
think
I had this last year (earlier than it showed this year), and it was
contributory to a fish kill due to lack of oxygen. It clumped into
malevolent black islands that rose to the surface during the day and
sunk
at
night, where it promptly consumed all the O2. This year I have
airstones
that I run 24/7/365. Where does it come from and how do I get rid of
it???

It is a Cyanobacterium (bluegreen algae). Oscillatoria spp. I
cannot tell the species from your pictures, but that probably
doesn't
really matter.

OK, I have a problem. My otherwise pristine pond water had
developed
suspended algae - large stuff. It *will* clump, but most of it's
being
removed by my pre-filter. I just posted shots of it on my
"website"
below.
There are microscopy shots of it at 40, 100 and 400X. If you have
any
ideas,
please let me know!
