Started off with a plan - 120 deep (used), a metal stand borrowing a welder, a couple of lights and pumps. 4-5k.
That quickly went to a custom 274 tank, then I upgraded that to low iron glass and some other features. Now I need more lights, more pumps and powerheads, more steel for my stand, purchased my own welder, more rock, and on and on….
I’m keeping track in a spreadsheet, and I have spent 14k so far and have an estimated 4k to finish setup (over the next couple months).
Then fish and coral.
I’m estimating that my tank will use $50-75 per month in electric plus an additional load on the AC during the summer (no idea what that will be).
Then consumables such as salt, additives, RO filters, replacement parts etc....
I tell my friends that it's like buying a boat and that's how I justify the cost.
(PS I don't own a boat for this reason. LOL)
I don't have to report to a wife so that helps.
