How do you guys control your Alk level?

[Dustin813]

Hey guys I’m having some issues controlling the KH of my tank. Not only is it a bit higher than I want, there is some fluctuation in the level as well. It jumped from 10.5 on Saturday night to 11.5 tonight. Ca, Mg, No3 and PO4 all test well in the tank and are at optimal levels. I did a 10% water change today, but shouldn’t that have brought it down a little? At any rate, how do you guys control KH in your tanks?

I had a huge swing in Mg few months back. I found out that the salt settles in the bucket over time. Give it a good shake n roll then do your salt mix.

I’m doing water changes with nutri sea water, so I’m not using any mix. I don’t dose alk either...it’s like my tank isn’t consuming it or something.
