FW: "Free floating" green algae
Staffan said he's having trouble with free floating green algae in his tank.
This is frequently called "green water" and can be solved in several ways.
UV filter, micron filter, filter shrimp or daphnia will effectively strain
the water and remove the algae. All are highly recommended. The use of
algaecides will kill the green water algae but will also harm any higher
plants in the tank plus suddenly release all the stored nitrogen (green
water will outcompete some biological filters based on info posted to the
Krib). So if you use chemical weapons :-) monitor the nitrogen cycle
closely. My recommendation is the micron filter followed by figuring out
what triggered the bloom in the first place. Try reducing lighting time
each day and monitor macronutrient levels as a starting place. Check out
the Krib home page for additional info

Doing maintenance on a planted tank, even if you get soaking wet, is better
than doing office work any day of the year.
