I've had a salt water tank running now for about 2 and a half years.
It started with a 10 Gallon then to a 30 Gallon to my present 90 Gallon.
I've had my ups and downs too, the worst being a tank crash a year ago when I moved my then 30G from my condo to my new house. I lost all my coral, I had over $1,500 worth of SPS and LPS die on me within 2 weeks of the move
and that just about did me in, but my fish survived so I just kept going, although I went into the mode of just doing the bare minimum husbandry to keep everything alive but really got passionate again about 6 months ago when I upgraded to the 90G.
