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!

When I first looked at your pictures and you said it looked like little
flowers, I thought it might be duck weed. Did you have duck weed in your pond
last year, where some of it could have survived. Or it could be just a strange
looking alage. Anxious to see what others think.

gave me the Rx for it it was Copper sulfate as in stump killer I dont
remember th dose now but it didnt hurt my pond plants you could do a

one thing I do know massive water changes dont stop it it comes back
jsut as bad after as before, when I tried that I dam near killed all my
fish due to temp shock as you remember

Good Luck keeep me posted as to how it goes for you

If it can't be fixed with bailing wire or duct tape
its not worth fixing

Welll .. it looks like my pond is afflicted with the same thing,

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???

Damn! I didn't want any problems this year (or *any* year, for that matter!)

I wanted to know what it is so I know how to control it.

Well, not knowing anything about UVs...maybe someone else can answer that
concern.

If it showed up in my pond I would -
* get around to buying a skimmer net

I have the skimmer net, as shown in the photos. Most of the algae is
currently getting sucked in the skimmer and caught by the window screen
pillow and the "bridal-veil-in-a-bag" that serves as my prefilter. But it
gets so full it slows the water down going to the pump!

(I have the catalog on my desk ;-)
then I would skim it off, which is probably what you are doing now, to
keep the
reproduction rate down
* stop feeding or cut way back on feeding the fish, especially if I had a
nice
fuzzy algae on the side of the liner.I would probably feed some veggies if
I
feared the fish would starve! I have two nice bunches of watercress in the
fridge now.

ACK! Quit feeding???? They like their veggies, but it doesn't take the place
of that stuff that goes "splash" when it hits the water. The only phase of
my water chemistry that's out of phase at the moment is nitrAtes, which are
running about 20.

* not wait for my shipment of water hyacinth and go down to the fancy
nursery
and pay major bucks for their sickly looking water hyacinth, figuring if I
have
excess nutrients in the pond they would perk those hyacinths up.I might
even
put up a temp. greenhouse over my filter to help them through the still
cold
nights.And hopefully the WH would starve the new algae that showed up.
One year I had this gloppy algae floating around, light green and in 5" by
5"
islands.
I plopped a water hyacinth in the middle of each gloppy island and it was
gone
in a week.

Duh! WH, of course! I have that stuff I purloined a few weeks back, some of
which is in the waterfall/stream (man, if that isn't wishful thinking, I
don't know what is!) area. I'll plunk that in the pond when I get home
(Bye-bye roots!) and rotate some of the puny stuff from the back yard into
the waterfall. If the roots last long enough, maybe they'll get the chance
to do something. If not, then the fish will have a fresh snack!

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.

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!

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

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!!!
