hello. i am on the verge of starting another saltwater tank. went shopping today to see what's out there. does anyone have any tips or do's and don'ts they wish to share? this is my second tank setup. the first one was 90 gallons. i moved 100 miles. set up the tank again and it was never the same. so we gave it away to someone else, then moved again. i just bought the saltwater for dummies book on ebay for a great price, and hopefully that will point me in the right direction. more than anything at the top of my list is tips and tricks to keep the paint from peeling off the wall behind the tank (another reason we didn't want to set it up in the new house). also, there are so many filtering systems out there, i don't know where to begin the research to figure out which is the best to use. so many choices!!!! does anyone recommend buying a tank/stand/canopy used or brand new. i also need to figure out what drilled and nondrilled means. let the fun begin. i will update as progress happens. thanks for any input that anyone can give me.
