so im looking for the stand to be at least 24inch wide for widthwise 10 gallons, 4 feet long to accommodate the 55. This, i hope, is the correct size to to hold a 55 gallon on top, 2 width wise 10 gallons, and a 20 lengthwise. or 3 10 gallons and 1 20H all widthwise. Most likely be the first combo. and i guess the top shelf about 4 feet tall and the bottom shelf a foot- a foot and a half off the ground. That should be enough clearance for the bottom tanks, hopefully. Let me know please how much this will cost/ and if there are any problems with my rough design currently.
