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.
