So, I have loved my freshwater tank but I have been seduced by the saltwater tank for sometime now. I, however, am on a budget. I am a college student and I pay for my own house. As stated above, I want to start a FOWLR 20g tank. I am a little bit confused on how I can go about doing things though. I do not really understand the concept of a sump, how to set one up or where to put it? Would a 20g tank need a skimmer? What equipment would I need for my 20g FOWLR tank? I will be placing the tank on the kitchen counter, a place where there is no disturbance as well as almost no sun light that reaches it. How powerful do my LEDs need to be for a 20g? I am very confused on how to set up a salt water tank when it is placed on my kitchen counter because all of the set ups that I have seen are in cabinets or on stands where they can place their sumps in places. How do I even set one up for my tank?!
