Thanks Rich and Kim.

A few more questions... Would there be a difference in cultivation for the non-tropical aldrovanda, ie. the green ones from Australia? Do you think it might work if I grow them in a large tank? Perhaps I shall try and see.

Is growing other massive root semi water plants / water plants and placing dried leaves in the water the only way to get rid of algae? I tried putting one cherry shrimp in my aldro tank together with dried leaves and other water plants the last time but it did not work.

Also can I know what media mix all of you use for the bottom of your tank? I read that we should use peat, but is this "peat" or sphagnum peat? I understand that some growers use normal soil.
