Thank you in advance. I have a 55 gallon freshwater tank. It has an
air-stone UGF. I have had this set up for about three weeks. Currently
it is home to 5 zebra danios. I have just acquired a Fluval 304. My
question is: Could / should I turn my filtering system into a RFUGF or
should I run both filters? I would like to have some live plants at
some time in the near future. I plan on putting some mollies, angel
fish, and pearl gouramis in the tank if this makes any difference.

Thanks again,
Kent
