Since I've found a PV I'm completely satisfied with and I have about 6 months worth of liquid, I'm saving a ton. I broke even easily within the first month. That's a good thing, but it's kinda sad considering how much I used to spend on cigs a month.
My profession says I should just save it all, but my aquarium hobby keeps whispering to me, "Spend more on fishies." Properly handling finances is all about compromise, so I think I'll put most in investments and the rest into my hobby.
I think I'll get my 90 gallon saltwater tank up and running again. I could easily drop about 5k into that tank considering each fish/coral/invert can cost between $25-$100 each, but I'll take it slow.
