Hello,
I have a tank around 150g with soft and LPS corals. There are seven fishes. The tank is one year old and was started with dead rock and sand. 6 months ago I also added live rock and now they are 50-50%. For several months I have had a problem with very high alkalinity 16 dKH. I thought I had the wrong test / Salifert / which showed a maximum dKh, so I also bought an AquaForest test, but it also showed a maximum. I decided it was my fault and ordered a Hanna - readings -- 16.3 dKh.
Parameters:
Calcium- 440 ppm
KH- 16.3 dKH
PH - 7.9-8.0
Magnesium- 1450 ppm
Phosphate- I can't exactly measure it with Salifert
Nitrate------- 40-60 ppm - I am dosing vodka and NO3PO4-X with little success
Ammonia - 0 ppm
The corals are alive but showing no signs of elongation.
Please help how to reduce dKh, to acceptable limits!!!
