Newbie Q- Opinions on UGF AND UGH for African Cichlids

Hi:

This is my first posting to this learned and amiable group.  I have just
scored my first aquarium in over 15 years and am slowly conceptualizing what
and how I want it to look and function, more importantly I have decided that
African Cichlids are my ideal pets.  However at this stage I want to plan
the tanks aquaculture as carefully as I can.  I have heard some good
opinions on undergravel filters and heaters.  I am however a little confused
as to what the setup might look like.  Is there anyone among you who has
experimented in the past or who currently is using such a system.  If so
could you describe what it consists of: How many power heads are you using 1
or 2?  Are you also using an external filtration system in combination with
the UGF.  what difficulties have you experienced with using an UGH?

Additionally recommendations on the various brands and models are requested.


Thanks in advance for your kind reply.


Sincerely;

M. DeSavoy
