Check archives. They have tons on this one. The easiest way is what is your
own preference. I use a magnum HOT 250 with a micron filter element and just
filter it out. Adding a UV sterilizer(8 watt Aquanetics) to this furthers
this process along faster. It takes about one day to clear and couple more
to completely rid the tank. Blackout, Daphnia, lower and/or redder light
levels, increasing NO3's, and several other methods are out there.
It's the easiest form of algae to deal with for planted tanks. Many ways to
kill/get rid of it. Many times after clearing it never comes back again. You
likely can go back to the old routine but keep up on things.
