Alkalinity is pegged...!

JammyBirch · 02/09/2015, 01:08 PM

Ok so I have upgraded my measurement capability by adding Hanna checkers into the mix. Just got the alk tester today, and ran it.

First of all this test took about a minute and I didn't count a drop...awesome.

Alkalinity in my tank right now is 10.4dKh...I think this is too high. Calcium is at 423ppm...which is where I'd like it.

I use a two part, B-Ionic, for alk, calcium and other trace elements. I use calcium to judge how much to add. Should I use alkalinity to judge the dose?

10.4 is not detrimentally high.

I cant get mine stable under 13 dKh >="(

I found out its my Reef Crystals Sal mix. Which is set at 13dKh *** IO!

You should always use alkalinity to judge the dose. Relative to the amount in the water, changes in alkalinity are much bigger. 1dKH change in alk comes with only 7ppm change in calcium. You can't see 7ppm calcium with any kit reliably, but you can see the 1 dKH easy.

Got a water change scheduled in a few days so all will be right with the world. I have almost never seen the alk that high with the titration kit. I'm in the middle of determining my weekly calcium depletion rate so I have been dosing calcium more often. May have over cooked it. I'll dose from alk from now on thanks.
