What ph to run in a calcium reactor

[Minuteman]

Can't seem to get the search to work. What PH should I be trying to run in a calcium reactor, please?

Typically, the effuent rate will be at 6.7; however it will vary a little from reactor to reactor.

Depends on your needs. I'd say keep the pH as high as possible while still meeting your calcium and alkalinty needs. For me its currently around 6.8 with ARM media. Every now and then I bump it down to 6.7 to give it a boost. Fully stocked SPS & Clam tanks I've had to keep at 6.5.
