I've managed to knock my heater last tie I did a water change. The tank temp has fallen from 83 F to 68F. Anything I should be concerned about? How quickly can I raise the temps?

I would raise the temperature for HEALTHY fish at the rate of as much as 1 *F per hour, but make sure there is plenty of water circulation so you are not getting hot spots, and so there is good oxygen circulation.
If the fish seem stressed stop, let it stabilize for a day or so, then take it up slower, perhaps as slowly 1* per day. Use a slower rate if this is a hospital tank, possibly sick fish.
I assume you are getting a new heater. Monitor it to be sure it is not overheating the tank.

It's an external heater and it's new. The issue was that I stripped all the pipes down and in doing so evidently knocked the temp dial which is very easily rotated. User error in this case. Thanks for the tip, I'd have been raising the temp a few degrees per day

Slower is safer, for sure.
