After going without a tank for over ten years I just setup a new 70 gal Oceanic. At the current time I am still cycling the tank. My question is..... The other day the local store owner was trying to sell me a refuguim filter, I made a wet/dry out of some spare plexi. I plan to have a reef tank (purchased proper lighting etc. from drs fosters&smith) but want to just go with some fish for alittle while. He told me a refugium would allow me to only do 25% water changes every 3-4 months. That just doesn't seem correct. Could someone please explain what are the pro and cons of a refugium and if I really need one.
Thanks -Tom
