Re: Is having/maintaining a SW tank harder/more demanding than a FW tank??
you can't really say sw is harder than fw or the other way because discus are harder to keep alive and maintain than tangs but starfish are harder to keep alive than bettas and bigger the tank in sw the more stable it will be but the more it will cost and more of a pain it is to change water ... what skimmer , filter and light is on it ?
