i have a 75g tank that i have had since june and i build the stand then. now im having a problem with the height of it. its to low to really do anything in my cabinet area. so i am thinking of build another stand and need to know what are some of the minimums that u guys have. cause i dont want to go through this again. right now im at about 20" and i'm thinking about atleast 30" maybe 35"
