I’ve been growing sps for a long time and recently added an Alkatronic and trident on to my sps frag tank 60gal. I’ve been looking at my readings/ graphs and what I don’t understand is why my alk usage varies so much. When I test manual (Hanna, salifret) it matches or within less than .2 of the Alkatronic (trident not giving trustworthy numbers still working on that). I dose with brs 2 part and kalkwaser (tank in basement and use kalk to keep Ph up. Kalk is on a versa dosing pump at 1.8 ml per minute up to 2500 ml per day and it’s controlled by my ph probe readings to high shut off. Dos does 28ml per day dosing something like 75 times per day. The one dip on graph was when kalk ran out. Ph low is around 8 ph high is just below 8.4.
I’m curious if other people have this much swing in Alk or if it’s just me.
