Equipment-wise it didn't cost much. The tank only cost $45, heater was about $15, and the light and hood I made out of sheet metal, wired in 2 light sockets and added 2x 10w 50/50 build that were like $20 all together. Lastly I added a LED
moon/actinic light that cost another $15 to make. So the whole tank set up cost around $100. I don't use any chemicals so no cost there.
The live stock is another story....I really have no idea but I'm guessing around another $200-250. Wow I never thought about how much i have in this little tank.
