Calcium reactor issue

[Potatohead]

If you can get it fast enough where it doesn't clog and still have the ph low enough to dissolve the media, that's probably the best option. Just make sure the tank ph doesn't fall too far or the alk rises too much.

The valve could be moved to the influent for more stable results. Also a PH controller measuring reactor ph will solve ph stability issues in the reactor if flow rate varies from time to time.
