Some enthusiastic replies there. I have algae in my tank that I'm desperately trying to get rid of. Whilst it looks nice on the rocks and pebbles that I have in my tank, it doesn't look attractive on the edge of the leaves of my plants. The algae I have is of a dark green nature and looks like smooth tufts of grass waving around in a field when the wind blows. It looks very soft and closely bunched up. I have a well planted tank, but this stuff is quite invasive. I can't use an algaecide as that would be to the detriment of my more fragile plants like Cambomba and the water parameters are well within tolerance levels for my types of fish. Short of pulling out all my plants which have been growing and flourishing for 3 years now, I am going to have to put up with it and keep it in check. Unless any of you out there has any other suggestions?
