Stable PH vs Stable Salinty? hm

[MammothReefer]

So I'm setting up a Litermeter to run of my AC jr.. and I was thinking I can either A. Use it to does Kalkwasser according to my current ph to keep it nice and stable @ 8.3 OR.. I can dose it based on time, to try to keep a nice stable Salinity. Lately I've been really feeling Salinity is a rather over-rater parameter, and that are corals and fish are perfectly capable of thriving in a wide range of salinity from say 1.021-1.030. While they only thrive in a small window of PH (and prefer very little swings). I also wonder which will be more stable. Will the difference in the amount of kalkwasser I need to drip to keep my PH solid @ 8.3 create a greater Salinity swing the, the PH swing I'll receive by dosing my kalkwasser at a drip rate to keep my salinity stable?


Thoughts?

While both parameters are important, id be more worried about the ph on a long term scale. The swing in salinity wouldnt be more more than .001-2ppm. Im far from an expert, but i dont believe it to be a big deal.

Only concern id have with controlling the kalk via ph is the size of your system. If you suffer from a chronically low ph, you should pay close attention to how often and how long the kalk runs. Never let the kalk mix run low. You could end up pushing freshwater into the system until it floods. On the same note, ive been dripping 55 gallons of unsettled kalk into a 6000 gallon system at night and getting a .2 ph spike.

hmm, well I can always set the MAX amount per day w/the liter meter.. So have it turn on and off based on PH, and have it dose no more then say 5 gallons per day, or just use the Float valve to make sure it doesn't raise the sump to high.

Right now my system runs around 7.8-7.9 so I'm trying to get it up to 8.1-8.3 and hold it there 24/7

I think you have a great plan.
