Geez...where to start.
Set up a 120 4years ago and had about $8K in it with LR, sand and that is it.
Ice Storm caused a 14 day power outage in the winter, I would have had to have 3 generators to keep everything going. Lost about $4k in livestock alone. I was in up to $12k at that point. Never the less to say I lost everything. So...what to do?
Buy a 225 Starfire and start over. I am using a lot of my equipment from my 120 including "base rock". After purchasing the tank, system pump, sump...etc, I'm well into the $15K mark and I don't even have water in it. Working on putting in a CL...it never ends.
Like others have said, I enjoy the hobby and love the life it brings into my home. My wife loves it, and she knows how much this stuff costs. All I can say is it keeps me sane, but totally broke!
