I am having no luck in buying a tank around 300 gallons in Las Vegas. Every place I find are all online. I could be looking at close to 2,500 dollars plus shipping. I am curios to know if building my own would be much cheaper and how difficult it would be. I could always go larger then 300 gallons which I would like to but it all depends on how much money this will cost. I have around a 1,200 dollar budget from scratch to completely filled filtered and on a stand. I would love any help you can give me. Thank you
