Im having a real hard time wrapping my mind around this. I have a well established 60 gallon SPS dominate tank that I run a small schuran jet stream calcium reactor on. My alk typically runs 6.7dkh to max 7.4dkh. 6.7dkh was more the norm as of late. Last month I was having issues with the circulation pump on the CalRx, so I did a total cleaning of the reactor, and I changed the pump. Since the overhaul, my alk has fallen to 4.8dkh to 5.1dkh. I’m trying not to freak out, and I don’t want to make any drastic changes. I’m slowly changing effluent rates, and I just lowered my ph ranges that control PH. I was closely monitoring my dkh after the overhaul, but I couldn’t stop it from falling with CalRx adjustments alone.
So now that you have that back story, to my amazement I do not see anything negative with the health of my corals with this incredibly low alk. My corals are growing and my colors on the sticks are actually improving.
All you stick experts who understand the science much better than I do, can you make sense of this? It is my intention to raise my alk back up to 7dkh in time. I would consider my tank to be ultra low nutrient system. If you guys need any other info on the system, let me know.
