I have a rimmed aqueon 40 breeder, there are gaps between the rim of the tank and the stand. I feel like a mat underneath the tank will solve this issue and alleviate my worries but I dont know where to buy one. Id prefer to buy something at any of the major stores (home depot, lowes, menards) if I can. The only thing ive found online (that is a big enough size) is an adhesive leveling rubber mat from BRS. I dont necessarily want an adhesive one and like I said id rather just buy one from a local store. tank dimensions are 36 3/4" L x 18 1/4" W for reference. Please give me any suggestions, below is a picture of one of the gaps.
