What level of nitrates have you got? 99 times out of 100 reduce the nitrates and the algae will go, simple as that...
Is it string algae (aka blanketweed, long green strands wrapped around everything in the tank), or hair algae (shorter brown, green, or black, strands growing all around and over the leaves of rosette plants e.g. Amazon Sword)?
String algae is most probably a nitrate problem, but could also be too much light, you often see it in ponds in the summer months.
Hair algae might be a lighting + nutrient problem, seems to occur most often where people are adding liquid plant fertilisers to the water, substrate fertilisers are much better... and more logical if you think about it.
Floating and/or fast growing stemmed plants might be a good solution to cut down light and/or nutrients, better that than spending lots of time and money on nitrate removing chemicals/sponges etc...
