There were several people at the Reef meet on the 14th that were asking about my levels, calcium, etc. I have just been eye-balling my top ups and chemical additions (a little of this/a little of that). I finally got around to testing my system today ( hadn't actually tested it since at last April/May?) and here are the results for my 130 gal display/ 30 gal sump:
Temp- 27 C
SG- 1.025
PH- 8.1
Amonia - 0.75
Nitrites - 0
Calcium - 425
Alk - 8 DKH or 3.2 MEQ/L
I did not test for Magnesium, Strontium or Iodine but they are all part of my regular routine. Amonia is a little higher than I'd like but not too bad with 24+ fish and all the other stuff I keep in there.
I checked my cal/alk against the chart listed below. Looks to be ok.
