I have been getting an itch to try salt water in the near future. I know the price tags are bigger. I am thinking totally from the standpoint of level of difficulty and hassle. One of my main concerns is what will happen if I want to go on vacation? Do I haveto have someone that knows what they're doing come take care of tank? Can I automate enoughstuff so that I can leave for a week (like auto top off & feeder)? Just in my "thinking-it-through" stage, so advice is appreciated. Thanks.
