Hi Mark
My 2 cent. Once you have achieved your desire Alk value, start the doser at night and allow it to dose small amounts during the day. I have mine dosing from midnight till 6 pm.
As you stopped your doser, now you will need to calibrate it again. I will be measuring every day, at the same time, let say 9-10 pm (in my cycle). And do small adjustments to the doser.
What I do when I have a peak of alk is to reduce the dosing volume and test alk every other day. To give time for biological adjustment. I will continue reducing the dosing until the doser and all the corals (with their consumption) give me a lecture of my final wanted Alk.
From there I just measure alk once or twice a week. Until I detect a deviation (+ or - alk than the decire) and start the adjustment again.
For example, now my Alk have been dropping slowly to 6 dkh and I have been adjusting the doser 2-3 ml (increase) per week to keep it around 6.5 dkh.
Then, something will change in the tank biology and corals will not be so active. As soon as it is over 7 dkh, I will start reducing the dosing slowly. BUT I never stop the doser !!!
Just my experience my friend. Corals looks AMAZING!!!. Keep those pictures coming.
Best
Daniel
