any and all advice would be great and highly appreciated.
what components are needed. overall use
how to setup.
I have a basic understanding for a sump but could use more advice
and totally clueless for refugiums.
I have a 70 gallon tank running with a sea clone skimmer I have an overflow box, there is a 100 pounds of live fiji rock in the tank.
I have a 33 gallon tank and a 20 gallon and 5 gallon.
should I use the 33 and partition it?? or use the 20 and 5??
also some assistance in setting it up may involve free beer
