the stand is iron,solid,center braces,painted with three coats and could hold a sky scraper.You could drop this thing in the ocean and it would not rust.
its an air tower and two intakes but they are on the high side i agree.There use to be a silicone mess corner overflow which i took out and this is the best i could do with it.I am going to put a piece of wood in that corner to make it look nicer and too cover up the silicone i could not get off.The tank had 12 wholes plumbed in it?I left three open.
