What’s considered stable alk?

[BAMatter]

I’m new to alk testing and what is considered a tight alk range… currently have a low of 9.4dkh and a high of 9.74dkh by testing every 3 hours and dynamically dosing through my Hydros. Is this pretty good or should I increase testing frequency and try to dial it in more?

That is pretty stable, check out this thread. https://www.reef2reef.com/threads/w...o-be-stable-alkalinity-in-your-system.575815/

Mine varies between .2 to .6 to me if it's not over a 1dkh swing I'm okay with it. Need to take the accuracy variances of the test as well.

Yea ok, thanks. Was kinda thinking that a .5dkh low/high is pretty good, and that under 1dkh is still acceptable just leaves something to be desired.
