Over the last month, I have been raising the intensity of my LED lights. (I have a T5/LED combo.Two 54W T5 blue plus lights and 300W LED light. T5 blue plus are 100%. Blue LED at 50%, white LED at 10%. Lights 4-5 inches over tank water surface.)
Today, I realized that over the same period of time, my alkalinity and calcium levels have slowly climbed. So, I have adjusted down my dosing levels a couple of times - including today.
I have also observed that sps corals are encrusting and growing well, but lps corals (chalices) are stagnant or receding.
1) Is it possible my lighting is too strong for chalices?
2) Is there any correlation between light and alkalinity/calcium absorption?
3) Is there a sweet spot for lighting where alkalinity/calcium absorption peaks?
