I have a 30"L x 12"D x 22"H (35G Tall{?}) I used two 20 lbs bags of EC and about 15-20 lbs of Sand as a cap and its a nice thick substrate. The sand cap makes planting fairly easy. Some people have complained about easy uprooting in EC, with the sand I have had good success. Good luck with the tank!
