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.
