[Coral-List] Use of Germanium Oxide to Control Diatom Growth

I am doing some research using the tropical anemone Aiptasia
sp. and am having some problems with diatom growth in my aquaria.  I am
aware that adding very small quantities of Germanium Dioxide (0.0005g/l)
to the water can inhibit diatom growth, however I'm concerned that it
may also affect the populations of zooxanthellae.

I would be grateful to hear from anybody who has experience of
using Germanium Dioxide for this purpose, or who can suggest another
method for reducing diatom growth.
