Been wanting to get into the hobby for a bit now and have been lurking around for a bit. Yesterday I picked up a 125g that came with some rock and sand for a good price. Really wanting to plan this out properly and on somewhat of a budget. I am thinking of doing a 40 breeder sump with a 20 long qt tank. I think I want to do leds or a hybrid set up. I think I'm going to set up the 20 gallon for now and work on building a stand and a sump and gathering the pricey equipment for the 125. Looking for some advice on sumps, skimmer, lighting, and ATOs.
