[APD] Re: BGA, antibiotics, and cloudy water...and fertilizer

Ok, that makes sense...except all my plants are growing just fine.  I'm
trying to keep them in the tank.  After 2 weeks since I planted them, 6"
limnophila is breaking the surface and the ceratopteris is unravelling
around everything.  The ludwigia is crimson red and I pinch the shoots
regularly to keep it in check, the lilaeopsisis is popping up everywhere...
mind you, all but one of my Hygrophila corymb. are dying (I think they have
never recovered from my being forced to replant them a few times for various
reasons...the one that's ok only went through it once), and the echino.
angust. has made much of a move...but everything else seems to be growing
like wildfire.

Oh, and I tried to remove the BGA first, but it was growing over a mass of
Java moss.  Not an easy task.

Thanks for the help.  A water change would make me feel better.  I hope it
wasnt' too much of the other bacteria.  I'll be monitoring ammonia levels to
be sure.

And I'll look into ferts.
