Hi, last nite I accidentally turned off my alk auto dose on apex fusion. Upon realising that this morning, I turned it back on to resume the auto dosing. It was set at 8 dkh. But was at 7.6 due to being off that nite. After 2 1/2 hours, I checked on the log and found out that it was auto dosing 200ml every 30 mins. And a total of 1 litre was dosed to my tank. Raising alk to 13 from 7.6. May I know what can cause this issue? I've been running trident control dosing for 8 mths and it's been doing fine all along. Here are some screen shots.

It was set to ON the 200mL is the tell tell sign and that the intervals were ever 30 minutes. When in the ON position it will run for 8 minutes and be off for 22 minutes.
