Ammonia, APD and Medications

Thanks for the information.. I've clipped it and added it to my 
"permanent" file :-)

I for one would like to see the list continue if at all possible. 
 I've found this format to be very interesting.  OTOH, Irealize 
how much work Shaji has put into it, and will understand if he 
feels taht he can't keep it up.  I will make an effort to check in 
on rec.aquaria.plants pretty regularly too.

One of the biggest reasons I'd like to see the list continue is 
that because every one tries to be civil and polite, I think it 
encourages people to express their sometimes very disparate 
opinions with out fear of being trashed by someone who doesn't 
agree.  I hope we don't see people holding back on new ideas when 
we are completely out in the public view.  

I've seen how some other news groups have become dominated by one 
particlar view point, not necessarily because it's "right" or even 
the most widely held, but simply because it is the opinion of a 
couple of extremely vocal, usually unpleasant personalities.  I'd 
hate to see that happen to us.

Back in the days when I would still treat fish in a planted tank, 
I also had a bad experience with nitrofurazone.  I _can_ tell you 
that although my extensive stand of Java Fern lost almost all its 
leaves, it _did_ eventually recover.  Other plants weren't so 
luck, but I can't remember which ones any more.  

Now I quarantine all new fish. A current resident has two choices. 
 He can let himself get caught, or take his chances.  I no longer 
put medications in my planted tanks _ever_.

As far as it being a low tech tank is concerned, I am sure this 
isn't the problem.  First, I've had low tech tanks set up and 
growing well for much longer than that. Second, even if it were 
getting to the end of its life, you'd see reduced growth, some 
plants failing fast than others, and slow detrioration of 
conditions.  Everything wouldn't "just die" all togther.  

I suppose it's not so surprising that an organism that is as good 
at extracting small amounts of nutrition from it's surroundings as 
aquatic plants would be susceptible to taking up substances that 
were bad for it just as well :-(

As an aside, Rainbowfish, particularly if you are talking about 
Melanotaenia, Glossolepsis or Chilatherina sp. are pretty big 
fish.  IMO, 12 in a 38 gallon tank is pushing it.  For that 
matter, most of these fish, even in smaller numbers, do best in a 
tank at least 4' long.  You might have avoided the disease 
problems if they'd been in a bigger tank.
