Bio-filter (85 gallon) which is just full of green, gummy, slimy crap
constantly. I think I might be defeating my own purpose - have been rinsing
out filter and media weekly - it gets that gummed up. Last year we only

Thanks for any ideas, suggestions. I didn't want to add chemicals to the pond,
but I'm ready too now. What works? I have been using BZT, no help, no change.
Thanks, Cathy

Cathy is your water green or is floating algae you problem?

I'd recommend two things:

Clean out as much algae/debris you can. Stop feeding your fish for 2 weeks.
See if you see an improvement.

If your water is green get a UV filter. They're expensive but once you have
one you will not know how you lived without one. I know I can't live without
mine.

is your biofilter covered?
clean the filter every day if you need to get the green slimy crap off cause it is
smothering the biobugs. or, put some polyester batting in to collect the crud,
replace when it gets slimed.
sounds like your bioload has increased. what and how often are you feeding the fish?
can you shade part of the pond?
how much extra aeration do you have? I think BZT requires pretty good aeration to
break down organics. Ingrid

You could add floating plants for shade. Ours is at least half covered and
we've got clear water. My husband complains about seeing the fish, but just
push it out of the way and enjoy.

Here are my 2 cents only because I think I went through the same thing.
I could see 3 inches into the water and the plants were feeble at best.

first of all, no matter what, the fish like the algae, they're happy, so
be happy.

By washing your filter out every week you're washing off the bacteria
that will help kill the algae. You're also washing off the other
bacteria that remove the ammonia, but since you have such a small number
of fish that probably doesn't matter. If you want to know what I'm
talking about with regard to bacteria killing algae take a look at
http://www.koiclubsandiego.org/GRENH2O.html. This seems to explain what
is going on with my pond, even though nobody else seems to talk about this.

I have a prefilter to catch the gunk. I have a contraption with a 4' x
4' piece of nylon batting that I run the water through before it get's
to my filter. I rinse the batting out once a week and it has a ton of
green gunk in it. I have it set up so I can tell when it's getting full.

What kind of filter media do you have? I used to have something like
pea gravel (only much smaller) and it plugged up with the green crud. I
replaced it with media that has more open space in it. I use straws.
Strapping tape and stuff like that would work well.

It took a month for the filter to mature and help clean the algae out.
My pond is oscillating now. Some days I can see 2 feet down, some days
clear to the bottom (3 ft). I figure anything beyond 1.5 feet is gravy
because I can see the fish fine. My plants are doing much better. I'm
hoping some day I'll have enough plants that are healthy enough that the
green gunk in the prefilter won't be a problem anymore.

Good luck.

Matt

Nutrients for algae are sun, new water, fish waste, fertilized run off, rotting
plants, blown in dirt.
Dry to reduce or eliminate one or more of these.
I agree with Ingrid, try shading the pond.

85 gallons seems like a small filter for 4200 gallons...

....stop feeding fish
....add floating plants to compete with algae and to shade pond a bit
....my understanding is that bzt eats mulm...maybe you are feeding your algae
blooms with dead mulm...stop bzt for awhile

This may be obvious but I take it you're cleaning the filters with
pond/de-chorinated water and not tap water?

I put a UV on my pond this year and I was happy in a little over 24
hours. I have a 30 watt uv on 1350 gallons. My pond is full sun--all
day. I get some floating algae on hot days, but it goes away at night
or I skim it off. I notice some variation in the water during the day
as the algae tries to grow but the UV catches back up at dusk. I
think my $230 investment was well worth it.

not if this is the gross or mechanical filter, and not even if it is the biofilter as
long as treated water is used. the biobugs adhere in colonies to the filter
material. what is normally rinsed off is the mulm and silt that are covering the
colonies and keeping oxygen from them. Ingrid

I was thinking of the green gunk I see, in which case the water has to
be under pressure and probably comes from a hose. I suppose this might
not be the case. Then again, if the media is full of gunk, where's the
bacteria going to sit where it's not smothered by gunk and is in contact
with passing water?

[I did say, Cathy, that not everyone agrees with that web page, but
everything it said alligned with what I saw in my pond more than a lot
of other things I've read. I have 1300 gallons, not many fish, some
plants, and had lots of soup until I got my filter working.]

Try reading that web page I referenced. He says shading the pond to
remove algae is a myth, as well as the idea that algae blooms are caused
by various nutrient concentrations. Based on his tests he said that
there's a byproduct from a type of bacteria that consume dead algae and
that is toxic to algae. So, Cathy's pond or filter needs a place for
some amount of rotting algae and it needs to sit there for a month.
This is why I said some sort of prefilter would enable Cathy to leave
her main filter alone long enough for this other type of bacteria to do
its thing. This is exactly what I did and now my pond is clear. This is
after 2 years of trying things I read on this newsgroup and getting
frustrated, as it sounds like Cathy is.

A uv filter would also kill the soup type algae and would do it sooner.
But eventually the filter will have to work correctly because the
fish load will increase to the point where ammonia is a problem. Of
course, with 4200 gallons and 2 small koi, 2 tiny koi, and 40 small
fish, this is going to be a few years. Anyway, as soon as the filter is
working the uv filter might not be needed anymore.

Since I just talked about Norm Meck's web page with "~jan JJsP" (see the

I don't agree with him.
Sun is a nutrient for algae.
It's called photosynthesis.
Also disagree with him about various nutrients.

I think putting in a mech/bio filter works because
the mechcanical filter works because it collects some of the mulm in the
mechcanical part. And that is why people think the biofilter is the magic
bullet.

I've had a clear pond for years. I think that gives me the right to post my
suggestions.
I took out the web page you referenced. Caused too many problems here lately. I
originally included it as just another idea but I don't like the tone of the

Now you can reference all you want but I stand by my assertion that shade will
help cut back on single cell algae. And too many nutrients are not a good
thing, for algae, for fish.

Yes, I read it, it drove me slightly batty so I removed the reference to his

fish here. Since you are signing off this thread, I'll include this in email.

I'm pretty much going thru the same thing. My pond is 2 1/2 summers old and
with patience it will clear, just keep things clean, stocked with plants and
don't add fish stock (mother nature will do that for you) time is the best
additive.
