Why this week's w/c went against my feelings

I recently got some salvania, but I've always avoided duckweed up to this point. Duckweed is many times smaller than salvania, which is why it is such a pest. That said it only took salvania about four weeks to go from a dozen plants to covering almost every inch of my 20H tank.

Weird. Mine just doesn't seem to be spreading any. I'm wondering if some fish are using it as a daytime snack

I had a huge water lettuce infestation at one point. I still have it in one tank where it doesn't seem to grow very fast but in other tanks I was clearing half the tank surface every couple of days. Nice looking plant, but it did keep my tanks rather dim.

Basically all my salvinia is gone. I'm not removing it with my pwc, so my fish must be loving it. I need to find something hardier I guess. I do like pennywort. I have some planted. I think I'll get some as a floating plant too (the planted one isn't big enough to cut yet).
