I just started my first ever tank last February, so I had a lot of up front hardware costs and then spent a lot over the past 8 months on livestock. My monthly average will decrease as I fill the tank, and I have stocked up on all the spare parts I intend to keep on hand (extra return pump, powerheads, etc.)
Since I charge everything on the same credit card, I was able to put together a quick report:
See, it all pens out to just less than ~$20,....K, ok!
