Alk and Ca

[drew2005]

Is it possible to have kH of 9.0 and a calcium of 360? I have a feeling my calcium test is giving me false readings. Its always 340-360. Think it might be time for a new one. Its only a few months old. Here are all my readings...
ammonia - 0
nitrite - 0
nitrate - 10
ph - 8.3
sg - 1.024
Ca - 360
kH - 9.0dkh
Phos - .10 (cant understand why its so high, hope my corals make it)
alk - 3.20
Mg - 1290
Any advice on what i need to do is much appreciated. It is a reef tank.

It's very possible... but a double check with a second kit isn't a bad idea.

Agreed it is possible, my tank was there before. I looked at your params and see your magnesium is a little lower then I like to keep mine. I found that if I keep my Mg closer to 1500ppm but no lower then 1400 then it is much easier to maintain my Ca levels where they need to be. I would reccomend increasing your mg then dose for Ca. It has always worked well for me.
