I'm a longtime FW
tank owner that has had success. I am looking to start off a SW
tank this summer. As a college student, I will be on a very limited budget. I have the basic necessities of a FW
tank including a 20G tank, light, heater, filter, etc. I am wondering what sort of investment I will be getting into if I undertake the most beginner friendly and basic SW
tank I can. Under $300?
