They are just a bit higher than ideal. Calc @ 525 Mag @ 1600 and kH @ 10. The only thing being dosed into the tank was a bit of kalk at the start but for the last week I have just used rodi for top-off. I plan on switching to AF Reef salt very soon and think that will bring the numbers down to a more ideal range. Once the numbers are in order I will start with AF Components 1,2,3.
