For this project we had a budget of $2,500 but ended up going over budget by $551.06. In total we spent $3,051.06 to complete our prototypes. The primary culprit for why we ended up going over budget would have to be the 750 gallon tank. It initially cost $727.99 but when accounting for shipping ballooned up to $1,756.20, which accounts for 57.6% of the money we spent.
