small gap between tank and steel stand like 8th of an inch about foot span can i use a peice of 3/4 ply or half inch styro?? i like the ply as i can paint the edge blak so you dont notice it as styro you will notice that alot more. or many i could shim it with metal strapping??? like that metal ribbon stuff?? the peice of ply came withe the tank and had the styro too but forgot it!! the tank is a 240gal 8x2x2
