I have a 125 gallon mixed reef with a 33 gallon sump. I use a Hanna checker to test my Alkalinity. This morning at around 8:30 the Alk was reading 8.7 dKH, and today at about 6:30 PM it reads 8.0.
Is this too large of a swing for Acros? Do I need to start dosing twice a day instead of once? Invest in dosing pumps? What would you recommend as the best course of action?
Calcium typically drops about 15-20 PPM within 24 hours as well.
Edit: I also forgot to mention, my means of replenishing Calcium and Alkalinity right now is strictly 2 part, but I'm open to other options.
