Refugium style tank with scrubber?

[tanan]

As my 20G leaked and I dont have the patience or money for reef,I was thinking of going to refugium style tank.
Do you think scrubber ll do any good to a refugium style tank ?
Any advice or ideas ?
I already had a working scrubber in the 20G before it leaked,so making and setting up a scrubber is no problem but is it needed for a refugium tank ?
or not like for FW planted tanks.

If you mean should you have chaeto or caulurpa, and a scrubber, the answer is no. If you mean anything else in the fuge (besides green), yes.
