I would think it depends on the tank size and the amount of water movement (filtration). For a 75g tank with a 50% WC and a canister filter I'd wait about 1 hour.

Water Change Question
Hello Con...
How long has the tank been running? Is it cycled? I change half the tank water weekly in my cycled tanks and don't test the water. By flushing so much pure, treated tap water through the tank, that guarantees there's no time for pollutants to build in the water before the next large change, so you have constant water stability. It makes water tesing unnecessary.
If the tank is still cycling with fish, then after a 25 to 30 percent water change, you don't have to test for 24 hours.
