There are a number of pieces of aquarium equipment that you can make yourself better and for less money than what you can find online or in your LFS. You can probably build that custom aquarium of your dreams in less time than it takes to mow your lawn and at a fraction of the cost to buy it. Or, you can build that custom aquarium cabinet and canopy you've always wanted in your spare time. Or, you can eliminate daily aquarium or sump top offs by installing a DIY Auto Top Off & Filtration System for less than $50. Take a look at the Top Aquarium Do-It-Yourself (DIY) Projects to see which ones you want to do.
