I used Devon's tap water with no issues.  
I suggested upgrading skimmer and new bulbs.  
And j. I'll test your water for you tonight to see if there's a diff between readings.  
 
The tank only has 4 fish in it but lacks a cuc. Also suggested a refugium to grow out Macro  
 
Tank was also started using prodibio startup
