Hey everyone, For those of you with sumps, has anyone experimented with duckweed in the sump as a phosphate remover. I was thinking of putting a small 15 W bulb over my sump and letting duckweed grow there early in the cycling process, which is when I seemed to have my worst algae problems. After all the other plants are settled in, though, I'll probably remove it. Anybody tried this? Thanks, Roni
