I'm not sure why the Anacharis would be melting, unless it just has to adjust to no CO2. I had a UG filter until recently on half my tank. I noticed on the half of the tank that had the UG filter plate, that the closer to the PowerHead (where suction/water movement increased) the slower the plants would grow. When I had Hygro difformis right next to the powerhead, it did not grow AT ALL. When I moved it, it exploded with new growth. However, when I planted Ludwigia repens in the same spot, it grew just as well as anywhere else in my tank.
I don't have any educated guess as to why that is.
