   Hi,
   
   I will be changing the gravel in my 55 gal tank to black flourite next week when I get more plants. It's been suggested that I do it in sections rather than all at once. Either way, should I use purigen, zeolite or matrix carbon to prevent an ammonia spike?
   
   Thanks.

   I used Purigen for very long time now, every thing seem to be fine
