Default Coolant mix not quite right

1996 Z71 1500 5.7L
Basically straight water was added to the radiator, not distilled, about half gallon, maybe a tad more. This was done while filling it with the correct 50/50. So the ratio is a little off should I be concerned about this? The temp gauge when warmed up now is a few flicks under the standard 210 operating temp, it doesn't seem to rise above that after driving for a while.
. I was thinking of doing a flush anyway, any good ideas or tips on a system flush? I've heard of people using straight water and mixing a cleaner in, running it for 15-20 min, dumping that and starting over with fresh 50/50.

Any tips or help is appreciated thank you
