PH or Calcium/Alk/Salinity stability, which is more important?

[wzero]

My SPS dominated use Kalk and a Ca reactor as calcium supplier. My Kalk dozer uses a float switch and a timer combination for dosing control. Now I set the timer to dose more kalk on light off to stablize PH. But since corals consumes more Ca during light on thus I should dosing more kalk on light on...

Well, in my opinion, PH and salinity are the most important as far as stability. Cal and Alk are important too but minor fluctuations in the latter should be too much concern.

The reason some people only dose at night is because photosythisis keeps the ph up during the day.

What other people do is light their fuge and put it on a reverse light cycle. This helps keep PH level 24 hours.

The answer is that they are all equal in importance. In the wild, the corals have stability in water quality and parameters 24/7. Do your best to replicate those conditions! BTW, in my experience, corals consume more calcium at night since that appears to be when they build their skelleton. During the daylight I was under the impression that they were taking in light and storing the energy needed for their nightly building activities. I may be wrong though, but I could swear I read or saw that on TV somewhere.

Storing the energy needed for their nightly calcification activities... intertesting!

this is like asking is food, water, or sleep more important?

my thoughts exactly.
