Best dosing techniques

[jason604]

So what do u guys do with optimal results for dosing a sps dominate tank?
So far I'm dosing alk 16x for 12hr after lights out then cal 16x fr the day. I do notice my alk drop from 8kh to about 7.3 or so. Is that too much fluctuation? Should I just split them on a 1hr alternating schedule?

I dose every other hour throughout the day from midnight to midnight. I stagger the two with alk being on the even hours and calc being on the odd hours. There's virtually an infinite combination you can do and I'm not sure there is a 'best' schedule. I'd just try to keep the dosing as steady possible. In my mind, smaller more frequent dosing is better than larger less frequent doses.

I dose Ca for 2 or 3 hours during the day, and Alk for 3 or 4 hours overnight. I manually dose Mg with my water change every 3 weeks.

I've had to increase the dose concentrations quite significantly over the last several months, esp the Alk. And now have to dose Mg as well, as that was getting pretty low now, too. I am sure it is all due to my SPS growth, as it is getting really crazy lately.

I'm using a 2 head pump for Ca and Alk, dosing once an hour into my sump with the drip lines separated by about 12". Mg manually followng RHF instructions for when Ca/Alk jugs are done.

GHL doser randomly doses Alk, Ca and Mg (7 times per day).

I heard dosing alk is better during lights off due to ph fluctuation?

I dose alk on the hour and cal on the half hour , 24 hours a day.
