I’ve set up a new red Sea 625. It cycled a month or so ago. I’m running a refugium, carbon reactor, a protein skimmer with a C02 scrubber. I have six fish and about 15 small frag’s in the tank. I used Red Sea coral pro salt. I’ve been dosing via kalkwasser mixture of 2 tsp/gallon in my ATO
Temp - 79
salinity -1.024
Nitrate - 6
Phosphate - 0.0
Ph - 8.1
Mag - 1370
Calc - 330
DkH - 4.5
the bottom two numbers keep plummeting. I’ve tried adding additional kalkwasser into the tank. I just put in 10 oz of alk 2 part liquid today, and it dropped from 4.9 to 4.5.
I’m completely out of answers. The only thing I can think of is the rock is consuming it. Is there any way that the new (still white) Marco dry rock I used in this new tank could be leaching out the calcium and alk? I used a lot of mortar in therock.
