My calcium is coming in at 480.

My calcium is coming in at 480.

FWIW anything over ~450 is not necessary or even beneficial. If you are using any additives that contain Ca you may want to decrease the amount some. A good place to be IMO is anywhere between ~375-435 ppm. That will provide Ca for all the animals, etc. that need it, while assuring levels don't get too high or low. It also allows some room for any test kit errors/inaccuracy.

I shoot for 420 ca and 8.4 dkh for alk.

Man, I really need to raise my dKH then. It's only testing out at 4.....

 

[chase33]

What test kit are you using and are you sure it's 4 dKH and not 4 Meq/L?

380-400 ppm Ca
8-9 dKh alkalinity
1140-1200 magnesium
