Blue-green algae / cyanobacteria? Or is it something else?

Suggested? I'm telling you my experience.

Sorry, I don't remember who suggest it. I didn't mean you did.

No I rememebr the guy that did. He was the only one and he's missing
something.

And no, I'm talking about all algae. I've done this many many times and
it has yet to fail.

You need to get all the dirt out of the tank too, but that goes
without saying.

The gravel is thoroughly vacuumed twice a month like the 55 that doesn't
have the problem. These 2 tanks are set up side by side (on the same day)
with everything being equal, yet one has a harmless green algae and the
other this nasty looking black stuff. :-( I don't want to waste money
adding more plants when I know this stuff will grow over them and smother
them.

Well, there's ammonia in there or you wouldn't have algae and it is algae
(or diatoms, same deal).

Remove all you can.

Change 80% of the water for two days.

Add Flourish excel. Fetilize with PMDD.

Do buy new plants, they'l be ok, honest. Hornwort would be best. Lots of it.
(unless your fish eat it, floating water sprint would be good too).

in the green tank, blackitout for 3 days then do the above. If you
do all thse things and don't miss one it shoudl be fine. That's
really all I do and it only takes a few days to bring the worst tank
to crystal clear newness. And I've had more filty green tanks than
Cartes has pills.

A test the other day showed Nitrates at 20ppm and ammonia at 0.

OK, I have the Flourish excel but what is PMDD?

All my hornwart died in the last 3 months after YEARS of thriving in my
pools, ponds and tanks. It's not always easy to find here. It just stopped
growing in *all* the tanks, looked sicker and more miserable until I tossed
it. That's another thing that's really weird. What would make all the
hornwart suddenly fail? I bought the original clump back in 1989 when I was
living in town.

The small amount of green algae doesn't bother me in the other tanks. It's
the tank with the blackish red sooty crap that's got me bugged.

Just like a car engine needs fuel, spark air, plants need light, food
and water. It didn't have one of them. Given you have algae I'd say food;
it stareved to death by running out of some nutrient.

I'm not aware of any chemical naturally (or unnaturally) exisint
in water that will kill hornwort. For example mosses are very sensitive
to sulphates. I've never heard hornwort is - doesn'[t mean that's the
case,I've just never heard it.

Excel should turn this white almost overnight. Despite the warning not to you
can safely double dose. There's a healthy safety margin built into this
stuff.

Is PMDD a separate product? The catalog doesn't say. If so, what is PMDD
and were do I get it?

Poor Mans ??? Dosing

A program of nutrient dosing based on simple ingredients where you "roll
your own" to suit your environment and plants - see Tom Barr's website
(don't have a link here at present but can search for the "Barr Report"

I have it in my tank and a 55 gram can not be Get rid of it. It started, almost looks like black soot, it is a deep Reddish brown. Add extra lighting, to encourage it to grow algae Even faster.
