I've had two attacks of green water. In both cases, only a 90% water change
got rid of it. Reduced lighting and partial water changes did not work. I
started using PMDD at the time of the second attack, and so far, with PMDD
and weekly 33% water changes, the greenies are gone. Also, since PMDD, my
plant growth is teriffic, and I've got very little algae on the glass,
plants and rocks.
