I have just purchased a Cal Aqua drop checker, reference solution (4dkh) and indicator solution.
When I half fill the drop checker with ref solution and add 2-3 drops of idicator solution the miture turns Green.
Should this happen ? After one hour in the tank it is still Green.
From what I have read I expected it to turn Blue! As at this time the CO2 injection had only just switched on.
Please advise accordingly, your advice is appreciated.
Kindest regards: Peter
