If all else fails, I always use water sprite. It seems to grow anywhere. I have anubias, val, crypts, java fern, java moss, hornwort and one very resilient swordplant. My water sprite grows from the bottom to the top and emmerse in my 55. My lighting levels are not extremely high and I don't use CO2. I don't have a huge algae problem except in the tank without plants. I can't seem to keep plants with the african cichlids, maybe it's the
pH, maybe it's the fish. Can't wait for spring so I get the pond going and get the pond plants going again.
