For cover to support tank base.
 
** How to order
1. Firstly measure the length and width of the panel where you are planning to stick vinyl. 
2. Measure the area by simply multiplying the length and width.
 
like if your tank size is 2ft*1ft*1ft and you are planning to put vinyl in the back panel then your back panel measurement will be 2ft*1ft and the calculated area will be 2ft*1ft= 2sqft. like for 1.5ft *1ft*1ft the measurement of the back panel will be 1.5ft*1ft=1.5sqft.
 
3. For placing an order put the nearest higher decimal value of the area in the unit like for 2sqft the unit will be 2 and for 1.5sq ft the unit will be 2. otherwise it will be a problem to process your order and create unnecessary delay.
