I've read both - the packaging says they are safe for all fish and best when used in combination. Anyone have experience using both?

Will they kill the biological filter?

THANKS!
 
i've used melafix a lot of times in my cories' and pleco tank without any problems, and i used pimafix a couple of times without problems either, but i just dont like the smell of it.
