My new sulphur denitrator setup

[TRS]

Have either of you tested and logged Calcium concentrations within your display tanks and the Sulfur Denitrator effluent?

My current parameters are as follows:

DAY 31 TANK PARAMETERS (March 8/07)
pH: 8.4 (by MILWAUKEE pH meter)
Specific Gravity: 1.025 (by ATC refractometer)
Temperature: 79.8 F
ORP: 362 mV (Red Sea Aquazone Plus 100)
Alkalinity: 3.52 meq/L (by SALIFERT)
Calcium: 450 mg/L (by SALIFERT)
Magnesium: 1380 mg/L (by SALIFERT)
P04: <0.03 mg/L (by SALIFERT)
NO3: 50 mg/L (by SALIFERT)*

DAY 31 EFFLUENT PARAMETERS (March 8/07)
pH: 7.5 (by MILWAUKEE pH meter)
NO3: 100 mg/L (by SALIFERT)*
Calcium: 490 mg/L


My Sulfur Denitrator has nearly cylced. I tweaked it too much a couple of days ago so it should zero out again in the next day or so.

I have not been dosing Calcium in the display, yet its concentration remains a constant 450 mg/L. My guess is that the Calcium will be more readily consumed and will be reduced once the Sulfur Denitrator kicks in and the Nitrates can be kept at zero.
