More on Ammonia


Ammonia which is lethal can be converted to ammonium which is not lethal by 
reducing PH below 7.0.  Many "cheap" aquarium products use large amounts of 
sodium thiosulphate to reduce PH thereby converting ammonia to ammonium.  
Unfortunately, if your PH goes up the resident ammonium converts back to its 
lethal form.  Tropical Science makes a product (Complete Care) which breaks 
the chloramine bond and then converts the released ammonia into ammonium 
di-basic which is not sensitive to changes in PH.  I don't know about other 
products, but using straight sodium thiosulphate can be a problem.
