do i need to heat my saltwater while it ages?? i got it to perfect specific gravety and i was wondering if i need to heat it to get the correct specific gravity. in other words does heat matter?

Most plain form hydrometers are calibrated at 60F. As water temp rises/falls the calibration temp, your salinity readings will be slightly altered.
For example, if your measured SG @ 68F(20C) was 1.000 then the actual SG @68F is 1.000 + 0.0007 = 1.0007, at 77F it is 1.0000 + 0.0018 = 1.0018.
However, check with the manufac. to check the temp it was calibrated at.
Good Luck

Your replacement water should be as close to tank water temp as possible to avoid any temp swings during a water change.
