folks, need some help please...I have a 265G tank in which I dose kalk
using a drip system of about 2 drops per second, this maintains my pH at around 8.15 (night) to 8.20 (day) but it seems I'm not able to raise my calcium levels past 370-380, I have checked my magnesium levels and they were low, 960, so I raised it over several days to 1300 but I'm still having issues maintaining high calcium, my questions:
BTW, I use a Salifert test to test magnesium.
1. does magnesium go down overnight/weekly - is this something that I should be testing daily and/or dosing daily/weekly?
2. am I not dripping enough kalk
(when I meausure the saturated solution it measures at 1500+ on the calcium and 12.89 in pH - I have digital meters for both, they are new and calibrated - chemical tests show the same results)....? should I be dosing more?
3. if I were dosing too much kalk
, which I don't think based on the size of tank and drip speed, but if I were, would that bring my calcium and magnesium down?
oh yea, and alk
is at 3.75 meq/l - using an Instant Ocean test kit along with a NatuReef test kit.
I have being doing lots of reading from advancedaquarist and reefkeeping.....but I just can not make sense as to why I can not bring this up and keep it there...
temperature - 79 degrees
salinity 1.021 - measured using refratometer and digital meter
phosphates - 0
nitrites - 0 - measured used nutrfin kit and also instant ocean
nitrates 10 - measured using nutrafin kit and also have digital meter
lights on for 8 hours a day
any help would be immensly appreciated!
