I'm shocked, dumbfounded... In utter disbelief. And I don't know what is more shocking to me right now.
1) My little frag tank takes up 2.9 dKh, daily!
2) My system is currently at 4.8 dKh with no STN observed on any acros!
Man, I knew there was going to be some serious uptake in that tiny water volume (20 gallons) full of mainly SPS frags but jeez, 2.9 dKh daily!
I'm going to empty my kalk ATO, refill it with the max saturation of kalk possible which is 2 teaspoons/gallon. For me, the container roughly holds 7 gallons so 14 teaspoons should do it. I'm curious if that even makes a dent to the 2.9 dKh daily uptake. I may have to run 2-part or even run a CaRX on that little frag tank.
