Default 72-Hour Blackout Cure for Algae is Rubbish

Well, after 72 hours of total darkness in my 4' aquarium I removed the
covers and:
thankfully, the fish are all still alive,
most of the plants are fine (java moss has suffered),
a bit of the algae has gone, but most is alive and healthy.

So to those advocating 72 hours of darkness as a guaranteed algae cure I
say: Nonsense, it is a myth. Don't bother even trying it. I did, and it
doesn't work.

Umm, not sure if you did your homework beforehand or just got bad advice
from someone, but it only works for about 95% of BGA's(Blue-green algae) and
greenwater type algae. It will probably not work for
brown(diatomic)/film/spot/fuzz/hair/thread/staghorn/BBA inc.(red types).

Reassuring to know fish can survive 72 hours without food isn't it?
I tried the darkness routine for only 48 hours to treat Ich. Didn't
work for that either, but I feel better about missing a couple of
feeding times.

Fish do perfectly fine for 3 days without feeding unless they are young or
already ailing. Mouthbrooding cichlids go weeks without eating while
holding a clutch of eggs for example. Anyways, since darkness did not work
for your algae, perhaps you should be reconsidering what kind of algae you
have. Of course, microscopic examination would probably be needed to made
an absolute ID, but if you could post pictures (overall tank shot and
closeups are good) to a webpage, perhaps more directed cleanup suggestions
could be given.

For BGA is certainly does, I've never claimed it works with other
algae.
You did not do something right as far as my advice if you were trying
to cure BGA algae.

If you follow the advice it, does work.
If you do not, I cannot help you.

If 3 day blackout kills or otherwise harms plants, there would be no
mail order plant vendors.

At least you tried. Algae takes lots of trying. There are many types
and causes. To get any useful suggestions you will have to post more
specific information about your tank, light schedule and power, fish
population, feeding habits, etc.

A blackout does no good if your tank's nutrients are still out of
balance. You need to get those in line, or the algae will never go
away. You have to treat the source.

I agree with this. I would've personally done some scrubbing on more built
areas, done a major water change and then tried the blackout. Probably
for longer than 3 days, whilst not feeding the fish. They'll pick up
any loose particles.

Always worked for me.

Yep on a 4 week old seeded tank, but whether it was the darkness that killed
it off, or the plants and filtration kicking in and using up the available
resources could be debated I suppose.
