I'm new to saltwater aquariums in general... I'm working on building my 29g sump underneath my 72g which will one day be a reef tank I hope. I'm trying to figure out the difference in a return water pump and a protein skimmer pump. I just need to pump the water from the sump back up into the tank which is about a 4' distance for the water to travel. I have a Sicce PSK-1000 protein skimmer pump on the way (I got it dirt cheap from a friend) and want to know if that will work for what I need.:sad:
