Well it will come back if the conditions don't change after the blackout. I
have found that adding more plants and doing frequent water changes helps
prevent/reduce its occurrance - after a blackout.

... but I don't think he did the water change before hand, and I'm sure he
didn't add the KNO3. I'm willing to bet that if he follows Tom's advice
to
the T, he won't have this problem. Tom knows what he's talking about.
I've
found that out, and my only regret is not listening to him earlier on
issues.

Just my opinion though... Either way, hope the algae disappears!

Why go to all that trouble and cost when you can blackout of the tank
for 3 days and cost you nothing and is 100% effective at killing it?

Not sure why people suggest drugs vs something that is FREE and
effective.

Do 50% water change, add 1/4 teaspoon of KNO3 per 20 gal.
Cover with trash bag towels etc so that no light gets in for 3 full
days.
Remove CO2, increase water movement.

Do 50% water change and add the KNO3 back and make sure you dose
enough KNO3 for the tank take care of the tank regularly from then on
with dosing and water changes.

You need to put this method in your web site and detail it out, not
antibiotics.
It's Free
It's faster
It addresses the long term problem, (poor plant growth)
It's simpler and not everyone has access to antibiotics.
It's 100% effective also.
It's been done many many times all over the world.

The OP said that he did blackouts several times and the algae came back.
