The sms 122 will do just what you want. It will automatically turn
off if the ph gets to low and keep it running @ the rest of the time.
Hook it up with a timer though so @ night it isnt running@ least thats
what most folks do.

Why do they do that? I've never used the sms controller, but from the
catalogue listings it looks like any other pH controller with fewer
features. So, it turns on the CO2 when needed to kepp the pH down, and
turns it off when not needed. What's the benefit of turning it off?
