What is walt smith figi gold and how is it used?
I have no refugium..bare bottomed 120 gal with lots of live rock and a very cramped sump (no room for extras in that).

If I were to set up a refugium:
(1)what size
(2)can one use the "plastic" hydroponic containers rather than an aquarium
(3)how does one use the figi gold or other base mterial suggestions
(4)can you purchase a "return system" to hang on he back of your tank so you don't run the risk of flooding the refugium if the pump in it stops..or do you simply run it from a return stack so that the safety margin is built in with the stack
(5) what size return pump is common and what type is least destructive to pods
(6) what type of lighting does one use
(7)what does one grow in it to lower phosphates/nitrates, balance pH and cultive pods

Thanks for any input from those using a refugium.

??can you have a happy tank if you never have a fuge?
