We live outside of Dallas and have had a 30 gallon fresh water tank for many years. We are moving to a 90 gallon, in-wall saltwater tank. We are new to saltwater and are planning on taking it very slow, learning a lot and hopefully doing it right. The tank should be here in about 4 week and we are planning on starting fish only or fish only with live rock. This site looks like a very valuable resource to help us on the path.
