good luck with the new tank...you will want bigger eventually so why not go for it now (the price sounds right).... the only down size to bigger is the cost of salt and the amount of water you have to change out if you do 20% water changes...time,work and money...otherwise your water is more stable and your options of what you can keep, and the potential of a 130 gallon are incredible...take your time and set it up right, the folks here will help you figure the plumbing and what not...good luck, and theres probably plenty of folks here who would trade a smaller tank for that one if its too much for you....
