Tanks but no thanks

 Here is a very interesting article as reported in the Dallas Morning News.  I 
would like to see the original, if anyone knows where it can be found.

 Tanks but no thanks
 ATLANTA -- Bacteria might be unwanted guests on vegetables, but they 
 are welcomed by new fish tank owners trying to remove dangerous amounts 
 of ammonia.
 A study described in Atlanta suggests that commercially available 
 bacterial additives designed to encourage the growth of nitrifying 
 bacteria might not work as expected. Nitrifying bacteria convert 
 ammonia, which can be toxic to fish, into nitrate. But these bugs can 
 be sluggish, taking about a month to establish themselves. In the 
 meantime, fish can sometimes fall ill with a malady called new tank 
 Scientists from Aquaria Inc., a California company that manufactures 
 tank filtration systems, tested three additives. In comparison with 
 tanks that had no additives, the nitrifying bacteria didn't appear to 
 grow any faster in the tanks dosed with the store-bought additive, the 
 researchers said.
 The scientists theorize that the additives might not contain the 
 mixture of bacteria the tank needs. For new tank owners who want to 
 avoid diseased pets, they suggested keeping low numbers of fish during 
 the first month, allowing the bacteria to grow naturally.
