We had freshwater for years, and the wife and I loved them. Kid number one came around and its always been a focal point at the dinner table and living room. Visitors always liked it too as our freshwater tank was a little more elaborate than most. When I lost the whole tank during a heater failure while on vacation I was ready to go salt. 2 years in a a 40 and the kids loved it and wife was on board. I convinced her I wanted to upgrade to something huge, but was willing to wait for a deal, and I honestly explained how much it would cost, about a month later found a great deal, sold the old tank after converting and broke even on it. Now I'm 2 years in, several grand in the red, but I'll work my way out, 2-3 years more and I plan on expansions and growing out frags, I figure I'll break even in 8-10. I've kept meticulous track of how much I've spent and I waited almost 10 years to go salt, I'm the primary money maker and this is *my* hobby, I don't really have any other hobby that takes up the same amount of time or effort so that's how I've justified it, not that I really need to. The kids and wife all like it, its a focal point of the house, we're not moving anywhere, and slowly the kids are learning to help out.
