Starting to get into SPS corals since I've gotten my Nitrates and Phosphate more or less under control. However, since I've added ~12 SPS/LPS corals in the last 2 weeks (mostly beginner SPS), I've noticed my Ca keeps dropping even though my Alk is high. Looking for how to correct this situation.
Originally, I was adding 6tsp of Kalk to my 5 gallon ATO, but after talking with my LFS, dropped it to 5tsp to try and lower Alk a bit. But since adding the corals, suddenly my Ca has dropped below 400ppm for 2 weeks now. What is the best way to correct this?
Just for info, I just picked up a 4 head dosing pump, so dosing via that can be an option. I am wanting to head that way and just use the ato for pure RO ato duties.
Thanks!
