ok so I am puttin flexwatt into place, the tank sits on a wooden shelf. My question is can I put tinfoil between the flexwatt and the shelf and be safe in doin that? I will be using foil tape to hold the flexwatt in place. Also can I cut the flexwatt inbetween the black lines? The flexwatt I have is the 11" but i need to cut the length down some is it doable?? Thank you in advance
Cheers
