Ca Reactor pH

[fatcasey]

Just ordered a new lid for a calcium reactor with the pH probe port in it and wanted to see what everyone else is doing. I'm hooking it up to my controller and want to know where to set at which pH I should have the CO2 kick on and off at.
Any input is greatly appreciated,

I have mine go on at 6.7 and off at 6.5.

Kinda depends on the media. Some require lower pH 6.5 or so, some work at a higher pH, 7.1 or so. Keep the pH where the manufacturer of the media recommends.

thanks for the info, thats kinda what I was thinking. I have the coarse ARM media but there are no manufacturer recommendations on the box, its pretty thick so i'd assume 6.5 would work well?

I use the carib sea coarse ARM.
