You can buy circular weights to go inside of a tank boot, but I think they're 5lb apiece - maybe you could cut one in half and add half to each tank boot.kcanty once bubbled...
You don't really have boots on your tanks, do you?

Double tanks (or any tank) generally shouldn't be left standing unattended, so there's probably no real reason to leave the boots on.
