I would like to to do a dyi aquarium. I m trying to learn more about this and build a glass aquarium. Is the DYI route worth it (would the price really be lower than a new or used one) I cannot afford plexiglass that's for sure. I looked at home depots and Lowes and they where not selling glass for a 75 gallon aquarium. I looked at eBay and they have expansive prices, almost as high as a new one. What is the best route to get a cheap 75 aquarium tank. I m welling to buy an older one and reseal it and use it. I m new to this I can use couple advices on where to find a cheap one that I can afford.
