Black Slime Algae

Anyone got any good remedies for black slime algae covering everything in my
tank?? I keep cleaning it out, and doing massive water changes, but it
still keeps growing!! Arrrgghh!

Heavily planted tank
CO2 injection
ph 6.8

Have you tried reducing feedings? Or changing the lighting?

I have significantly reduced feedings... My current light (10k pc) is
almost 12 months old... I figured it would last 18 months, but maybe that's
it. Thanks for the heads up.. Until I replace it, maybe I'll try massive
water changes every other day..

You might try buying a timer so your lights can go off for a few hours
during the day. This helps stop algae from growing. So I was told in the
newsgroups and lo and behold, it works. The algae in my tank is nearly
gone---it has taken about six weeks, but the difference is amazing.

It might actually be blue-green algae which 1) can be a variety of
colors, and 2) isn't actually an algae, but rather a bacteria.

I've been struggling with an algae that fits the descriotion you gave -
black slime - and I'm giving serious thought to medicating the tank
with a general anti-bacterial agent of some sort.

See blackout method, this will help your plants and take less time, is
certainly the cheapest method and the easiest, fastest etc.

Remove the algae that's there, do a 50% water change, add 1/4 teaspoon
of KNO3 per 80 liters of tank. Clean filter before water change.
Turn off CO2/lights and cover so that no light gets in with trash bag,
towels etc.

Wait three days, remove the bags and turn light/CO2 back on, do
another 50% water change and add the KNO3 back and thereafter 2x a
week.

You do this, you will not have the BGA come back.

But you can try the other methods which are not free nor address the
root cause.
This method has nothing to lose and is 100% effective if you follow
the directions.

If you do a controlled mid day sieta, you will find it does not do
anything. If you have slightly poor.insufficent CO2, this gives a
chance for your unpowered CO2 diffuser set up to catch up since plants
stop taking in CO2 when the lights are off.

The light itself does not cause the algae to go away and the 3
blackout makes algae die fast, not weeks later and also helps to grow
the plants by adding what caused the plants not to grow well(lack of
NO3), which is why you have the algae in the first place.

I've read lots of comments that the blackout approach has little or no
effect on cyanobacteria, since they aren't dependent on light like
conventional algae. The tank in which I'm having problems isn't planted
(not quite correct - I've tossed a handful of najas into it to try to
out-compete the BGA for nutrients), and I don't do any CO2 injection at
all.

I believe my root causes are that I overfeed (which I'm correcting) and
that the tank is now so overrun with BGA that moderately drastic
measures are needed to bring it under control.

I've already started treating with Myacin. If the five day cycle
doesn't have any effect, I'll give your instructions a whirl.

They are indeed photosynthesising, why are they green??

You would feel much more accomplished if you defeated the beast without the
aid of antibiotics! Do deep gravel cleanings and clean out your filter
thoroughly, 70-80% waterchange. This will help alot too.

**So long, and thanks for all the fish!**

Here's what I discovered...

1. My light was definately shot... The new bulb was an immediate
improvement in the quality of light.. It was also nice to see my plants
"pearling" once again with two hours of the new bulb being installed.
Lesson learned, 11 month replacement cycle for PC bulbs!

2. When I refilled my CO2 tank 3 weeks ago, I NEVER TURNED IT ON!!! Ugh...

So between my light spectrum issues, and the fact that I haven't have
pressured CO2 in almost a month, probably has led to the massive imbalance
within my tank...

I'm willing to bet it returns to "normal" within a week or two now!

Thiose comments are patently incorrect. Nothing personal, but they
are.
It's that simple.

Anyone that does what I suggest(not their own modified version) on BGA
will agree. BGA are(the species we deal with), as are all
algae/plants, totally dependent on light.

Lots of comments that Blackout does not work?
Name one that has done the method I suggested in honesty, and it has
not worked?
Even one?

I've never read one yet. I do get many folks saying it did work on
BGA.
"Thanks! It's 100% Clear and clean! yada yada........."

Everytime.

Some one will say BBA and blackouts don't work, yea, I agree. But it's
100% effective on BGA which is the only real use for this method.

My question to you is have you tried it?
If you do, then you'll know.

I believe my root causes are that I overfeed (which I'm correcting) and
that the tank is now so overrun with BGA that moderately drastic
measures are needed to bring it under control.

It's not due to over feeding.

I've already started treating with Myacin. If the five day cycle
doesn't have any effect, I'll give your instructions a whirl.

Antibiotics do work, my point is not that Myacin does or does not
work, I just offers a better method that takes 3 days and is 100% free
and addresses the long term problem that you have.

Anyone can do it.
You can solve your BGa with that, or Blackout, but anyone that claims
the 3 day blackout I suggest does not work is frankly full of crap.

I've helped countless folks cure their algal issues for the last
decade. Check the APD, APC and other forums.
See this month's TAG, ask around.
