Any book will tell you brown algae is a diatom and occcurs in low
light situations and you can sure ut by adding more light. The
books seem to be unanimous on this are are of course flat out
dead wrong.

I have about a dozen 2 gal. tanks in a wondow; 3 of them have
small light loving killies (Aphyosemion cyanostictum "SAM")
and the rest are daphia cultures - enough to feed all my
fish in small amounts daily. The killies get daphnia and
occasional feedings of grindal worms. The Daphnia seem to
feed on infusoria and algae - I don't feed them any more
although I used to feed them green water (unicellular algae,
not Euglena)

The daphnia tanks get brown algae the killi tanks
used to get a film of green algae but in the last
week are now growing hair algae. Go figure.

I use straight vinegar. If you've never cleaned a tank with this
stuff you don't know what squeeky clean glass is. Is there
anything that can survice this treatment ?

Hmm, I wonder if I ask a question about Banana plants
get I get help with Tiger Lotus ? :-)

Lemme try that again.

I've grown these things before and they're one of
my favorite plants (I'm a sucker for red plants).
When I had them last time they were a round bulb with
a couple of small shoots sticking out. They grew
into a monster sized plants with huge red round 
leaves but the plant was a separate entity form
the bulb - there was one stem-like thing connecting
the plant root mass to the bulb. I moved before I
had a chance to snip it and see if the plant would
develop a bulb or if the bulb would grow another.

So, these bulbs I have now have no growth coming out
of them whatsover and if they wern't hard as rock
I might think they're dead. I know that they like
massively heavily fertilization and I'm tempted to
make a small pot with sheep manure and peat covered
with a few inches of sand.

My questions really are: 

        1) Do these things normally go through
        some sort of dormant phase, ie do I want or
        should I do something to kickstart them ?

        2) How deep should they be planted? Something
        tells me they should be in the manure layer
        and that might get them going again.

Anybody played with these things much?
