Hello. I am completely new to this and need help. I just bought a SeaClear Rectangular 30 Gallon Tank. I plain on doing a freshwater tank. I was thanking of buying a wet/dry aqueon proflex modular sump filtration system model 1 http://www.petco.com/product/114379/Aqueon-ProFlex-Modular-Sump-Filtration-Systems.aspx . Read that the wet/dry where easier to maintain. Is this what I need. If so what else would I need. I know I need a pump but what kind and how do I get the water form the tank to filtration system. What kind of heater would be good and do you put it on the tank or in the filtration system(read of doing it both ways). Basically I have no idea what I'm doing. Does anybody have some sort of diagram that shows the order and the stuff you need. Any help would be much appreciated. Thank you.
