81 is not excessive, unless you have some non tropical animals that need
colder water.
the only way I would disagree is in the part about "I have a new 125" if its going to be a
problem now when its *new* is the time to fix it, not next summer when all the sudden its
back up to 90F indoors, to many people complain about it down the road because they didnt
do something now.
