Maybe quitting Zeovit

[Johnny Reefer]

Hello,

I'm going to be starting Zeovit in a few days. Great thread. A good eye opener to pay attention to the system. Been reading up and asking questions through other various resources. One question I haven't asked of anyone yet. That being about the flow rate and the adjustment of. Looking to get an idea of how folks know they are at, say, 50-75 gph, or whatever. Educated guesswork? A certain postion of the handle? Timing it into a bucket for 1 minute? (I imagine the latter method being somewhat difficult, what with the reactor in the sump).

Thanx much,
