does a black out work for all algae problems?

I am able to rub the algae of the leaves today, not all of it but it is becoming easier. I will clean the intake tubes toningt to remove the dead algae that has come loose. I found the link to the use of excel to eradicate this algae very helpful, although it was a long read to get to the end... 27 pages.
 
ok, moved 36 watts of light to the 20 gal tank, moved 15 watts of light to the 10 gal, continuing to dose 2x normal daily dose of excel, fertilizing with seachem liquid ferts until my shipment from MGamer comes in and then I'll start them. haven't bought the timer yet will try 8 hours a day with 1.5 wpg. almost all the remaining dead algae is gone. CO2 consistant.

Keep going, repeat till most all of it is gone, manual removal, algae eaters, etc, hit it with good plant growth conditions is the main key.........then you focus more on growing and gardening plants(the goal), less on dealing with algae.
It can take time and a lot of effort to fix an algae issue, but in general, it's because there was poor conditions for the plants that led to it.

In the early 1990's, I spent 3 years straight dealing with BBA till we figured out is was CO2. CO2 is the one thing that will nail everyone if they stay in the hobby long enough.
You think you know it and think it's good/perfect/nothing wrong there etc............everyone has thought this only to over look something.

Never be too confident there and.......... the plants never lie. Nice growth= things are good, bad growth= things are bad. Fairly simple.

Many ways to mess up, few ways to do it right.
