Hi Everyone,

I thought I sent this question in yesterday, but I may have not
changed my subject line because I did not see it in todays digest.

I was growing 2 pieces of aldrovanda in a 3 gallon tank on the
windowsill. The tank has a substrate of aquarium gravel, a
mini-filter, a water hyacinth, some salvia, and a sucker catfish. I
have also added blackwater extract to the water when i set it up.
The Ph is 6.4. Last week I noticed some hair algae slowly growing
on one of the alds. so I took one and put it in a jar by the window
where I am keeping a waterhyacinth as backup. Over the weekend, the
tank developped a real algal bloom of that cottony type algae that
sits on the ground. So I took the other piece of ald. out and put
it in the jar. So here's my question. The jar with the hyacinth
has been at the window for over a month, and has some microorganisms
in it such as cyclops, really big osteocods, and several different
unidentified worms. I noticed years ago already that when I put a
jar of water by the window, it does not develop algae if the
osteocods are present. Searching on the web, I found out that they
are detritus eaters. Are they algae eat ers too? They never seem
to hurt my plants themselves. Would using them seem like a good
method to grow my aquatic utrics. and alds.? All I really found on
the net was their diet and distribution ranges. Any opinions or
facts would be welcome.

Also, I have noted that any time I use substrate of any kind in my
plant jars or aquariums, algae grows significantly faster than in a
bare bottom setup. I do rinse whatever I use well. I would like to
grow my U. Purpurea in the submerged form instead of the floating
form I have now, but I need something to keep it down with, but
everything I use seems to backfire on me. Any ideas?

Thansk again.
