And this is why using a controller is always simpler. No reactors require one just recommended to make your life and and tuning it so much easier. Good luck

I found the same issue with ARM coarse media. It has a hard time to break down. A lower PH is needed. Then after some time you will find the alk will start to creep up. It almost appears to have a skin on it which you have to break through then it will start to take off. Don't be alarmed if you notice your alk drop. I was told that on initial start up the media will absorb alk. before it starts to release it. Just give it some time. Next time as Jack mention Reborn media is coral bones and appears to dissolve at a higher ph and with virtually very little break in time.HTH.
Really? How has it worked so far?
Testing the alkalinity is a better indicator than figuring out your Ph.

UPDATE:
In the past 12 hours my Alk has STEADIED. It's still at 8.12 which was exactly my last reading. But this took an increase in settings.
Old settings...
Effluent = 65 ml/min
BPM = 68
pH = 6.57
New settings...
Effluent = 95 ml/min
BPM = 112
pH = 6.47
Think i should leave it be for the next 12-24 hours?
I'm wondering if its taking a few days for this media to really start dissolving.
Jack mentioned the lower ph that was needed with the coarse media and then this person also mentioned there being a bit of a lag in the beginning.
one difference is mine is used, so i dont know if there might be a build up in the gate valve or not. just wanted to see if it was a common thing that will settle itself out before i get proactive with it.
What is your target alkalinity? For example, if the target is 8.5 dkh, use a little sodium carbonate to raise to 8.5 dkh and the reactor will maintain that level. If the target is 7.5 dkh, turn off the CO2 (while leaving the effluent running) and let it drop into the 7.5 dkh and then turn the CO2 back on.
Last thing, measure calcium and mag to make sure it is at your target. What do you use to maintain mag? You could use zeomag/dolomite inside the reactor to maintain mag or dose a mag solution.
