Note:
When automating any body of water, it is essential to size the feeders to reach desired
levels in a relatively short period of time. Generally, automating an existing body of water with
existing feeders will require the output of the feeders be increased accordingly. If feeders are
unable to keep up with demand in a short period of time, automation becomes ineffective.
