I recently purchased a 75 g aquarium (48"x18"x21") and I cannot find ANY aquarium stands anywhere!! I am tempted to purchase some lumber and build my own, as I have built a few small stands out of 2x4's, but they were small stands for cube tanks. I have been checking Petco/PetSmart for weeks and they have been out of stock. I checked on Amazon and they have a basic 75g stand but they are asking $700!!! I know that building my own would be much cheaper. (even with the price of lumber going through the roof...I figured that I could build one for around $80-$90, but made out of 2x4's it would be extremely heavy. Any ideas?
