				Hello Nick, 
 
An alkalinity of 9/10 dKH and a magnesium of 1400 mg/L are within specification.  A calcium of 590 is not.  I checked the certified lab results and they show a calcium of 436. Have you double-checked the calcium concentration with another method or maybe you could have someone else test it for you?  
 
I suggest not using a heater and don't mix it too long to avoid excess cloudiness.  If you are using a large powerhead this will also cause precipitation.  Mixing too long or mixing too hard (as with a large powerhead) will introduce excess CO2 which causes precipitation of carbonates.  Elevated temperatures will reduce the solubility of calcium carbonate also creating precipitation.

 So I asked should I remove the powerhead and heater from my set up......
