Generally after a few hours. Perhaps 3 or less.

As for changing out the solution, every once a month is good.

20 gallon - Sulawesi Golden rabbit snails/Japanese Trapdoor snails/RCS/Marbled crayfish tank
55 gallon - Rainbowfish Dutch scape low-tech planted tank

250 gallon - Community Tiger Oscar/Red hook silver dollar/Silver dollars/PB Jack Dempsey/Clown loaches/Tinfoil barb/Roseline sharks/Bala shark Monster fish tank

The solution gets faded. Basically you will know when you need to change it. I change every month just because I like to keep it bright and easy to read.
