re: Filtration



Just a different twist on this topic - I was talking with one of our
venerable gurus, Al Castro, a few years back about raising fry.  Al
remarked, as best as I can state it, that some breeders fail miserably,
particularly with Epiplatys species, because they keep their tanks too
clean.  By that he was referring to the beneficial infusoria that tend to be
found in tanks with mulm (a word we don't hear much anymore).  A spotless
tank is not necessarily the healthiest one.

This disclaimer was intended to help those new to killies.  We tend to use
small containers and they can pollute quickly.  Water changes are
recommended.  But let me state that no one of this list has advocated a
super-clean aquarium as the be-all, end-all.  We have been talking about
ammonia and nitrite and things that are generally not visible.
Understanding those is important!  A build-up of mulm and algae,
particularly in an unplanted rearing tank, while somewhat unsightly, can
actually help your fry get through the tough first few weeks.  It's
something to think about...
