I have a 125 gallon reef and fish display tank with a RS Eshopp sump in basement. I want to add a tank for refugium and would like some input on what to use and what do I need to do so. I am thinking a 55 or 75 gallon tank. Do I buy a reef ready tank or simple one and drill holes and put some bulk heads in it ? Do you need baffles in it or just open and add algae Any body have diagram on how it should look ? Do I need pump to pump what from sump to refugium or just put higher and gravity ??
