Weird parameter readings
 

Tested my water yesterday and not sure what to think with the results

API alk 8
API ca 400

Elos alk 6
Elos ca first test 500 second test 430 (did the complete test twice)
Elos mag 1100
Ph 8.1
Salinity 1.024
Temp 78

Have not been dosing, but will get my doser set back up.

What numbers do I work with for the big alk and ca?

I found it was fairly easy to screw up the Elos alk test, so for that one I use Salifert. The Elos Ca test I love.
One good thing is that none of those numbers seem all that bad. From what I've read and learned I try and keep my alk somewhere around 8-9 (but it can certainly a couple points either side of that), Ca around 400-450, and my Mag 1400-1450.

But like I said other than a wee bit of tweeking (and only if you really wanted to) your numbers don't look bad at all.

They aren't horrible, but I'm not getting spectacular growth either. Elos alk test kinda sucks but just thought I'd do both just to double check.

Completed a water change this morning, will check again tonight and get my doser going.
