Very interesting article, kinda blows my hypothesis out of the water but
that is the way it is sometimes. I do know that what many hobbyists call diatoms
is really yellow brown algae that covers everything with a thick layer of
brownish slime. I don't think this is related to diatoms but I might be wrong. I
used to use a reverse flow filter on my reef tanks that was filled with very
fine almost totally white silica sand and sponges grew over every shaded
surface, under ledges and behind the live rocks. I honestly didn't know or
rather didn't connect the sponges with the sand filter.
