I have been dosing kalk for a couple months now and I am having a problem with high calcium and low alk. Currently I am at 470 calcium and 6.2 alk. I am using reef crystals salt at 1.026. Corals are growing, but I am struggling to maintain alk. I started dosing kalk based on my alk uptake. Ph runs 8.35 day down to 8.2+ at night. I primarily dose at night. I have an x1 with 12 times(1.5 hrs apart) dosing 112 ml of kalk each dose into my the return chamber of sump. Tank is 120g + 40b sump, I’m using 150g for my calculations. Current plan is to reduce my kalk a small amount and use Randy’s part 1 to dose alk back to 8.5 over the next couple of days.
what would cause calcium to be high and alk to drop every time I dose it back up?
on a side note note, I can now see the relationship between co2 in the house and ph. Every time we go camping (2 adults and 4 dogs) I get alerts that my ph is greater than 8.4. When everyone is back home it stays around 8.35 peak.
thanks
