After 1 hour later for testing ?

For dosing additives, after how long can we use the test kits to test.

After 1 hour, is it ok ?

Test first... then dose... when you dose, you ought to know how much you are dosing.

I know have to test before dosing any additives. But after how long interval to read the test again ?

Ideally, a few hours later... diff tanks have diff water circulation.

In a tank with a fast turnover... probably the time is shorter... but you have also bear in mind the dissipation rate vs the absorption rate of how fast the tank consumes it!
