Filaments of brown algae : problem in established tank

I have now had the new regime for three or four days: lots of turbulent
water flow, 12 hour 250W MH lights, activated charcoal, Kent
phosphate/silicate sponge, refurbished skimmer (collecting decent
amounts of gunk).

The problem with the algae persists. In fact it is worse, if anything.
When the light first comes on it looks better, but within a couple of
hours the tank is full of strands of brown filamentous algae.

Is it possible that my MH bulb is causing the problem? It looks as
bright and white as ever, but I'm clutching at straws now.

What to do next?

Thanks!
Julian

Maybe I'll add another powerhead to rough things up a bit more ...
can't do much harm.

Thanks!

Isn't brown Algae cause by pour water circulation? If so, shouldn't more
water movement fix this problem? ( before you flame me on this... I'm

asking, I'm not sure of the answer)
