Hey

is it right you can run a tank on just live rock as a filtration
system
and
don't need any other kind of filters?

No. You will still need filters for larger matter and to aid in water
movement. Also the equipment you use will depend on the type of tank
you
are using and the tank size. Give us more info please.

Tank size
Type of critters (Corrals, Inverts, Fish)
What type of substrate (Crushed Corral, Sand ect.)

With live rock you can however get rid of your under gravel filter. In
fact
this is a must.

Here would be my suggestions for a FOWLR (fish only with live rock) Based
on
a 55 gallon tank.

1. Live Sand - about 3-4 inches
2. Live Rock - 1/3 to 2/3 tank volume
3. One or two filters - large enough to move 3 times the water volume
each
hour
4. 4 Power heads or water pumps - Enough to cycle water volume 4-6 times
an
hour placed at different levels in the tank
5. 2 heaters - together rated slightly higher than the size of tank you
have
6. Timer for your lights - 10 -12 hours on a day

Although this would take you out of the FOWLR category, I would also
recommend a cleaning crew (hermits, snails, shrimp, ect.) as most folks
tend to over feed at first. Also about 4-6 small fish might be nice. :-)
but only add them two at a time at the most and only after your tank has
been cycled and tested. Then retest after each 1-2 fish have been added.
Ok I'm done for now. If any of the rest of you here would like to add or
correct please feel free. All the above is based on what I have done and
so
far everything has worked out fine.
