High Calcium - how to safely lower

[Intheflesh]

Hi Guys -

I just received the results from my ICP test, and had some interesting results.
KH - 7.35° DHK
Salinity - 36.44 (a little high)
MG - 1387 mg/l
Ca - 691 mg/l!!!!!!
K - 343 mg/l - a little low. I do dose Potassium Iodide Fluoride everyday, maybe need to bump the dosing a little.
Iodine - 412 ug/L - a little low
PO4 - 0.01 mg/l
NO3 -1.09 mg/l

I am running Zeovit, so my PO4 and NO3 levels are expected to be very low. I know that Zeovit tanks are usually K deficient, and the test shows I am a little low.
What surprised me is my Calcium is near 700! What is the best course of action to get this within range?

I am dosing using the Aquaforest 1,2,3+ DIY recipe, dosing 30ml of each solution daily. All 3 of my dosing containers are at the same level (0.8L / 1L container), so I can eliminate dosing extra Ca solution. I am wondering if I messed up my last batch of Calcium solution since Alk and Mag are in range.

I think my game plan is first confirm that the ICP test wasn't a fluke, then do a 20% water change, mix some new CA solution, and maybe cut my CA dosing in half for a week. Any other suggestions?

id stop dosing calc and only dose alk for about a month ive had this problem too

Cut back on whatever you are dosing to raise it and do nothing would be my advice.

try that test kit on some new salt water to help validate the accuracy.
