Abstract

Apparatus for controlling the environment of a tank adapted to be filled with water where the tank includes a plurality of control apparatus. The invention specifically utilizes a microprocessor having a plurality of control signal inputs and a plurality of control signal outputs. Apparatus is provided for coupling each of the control signal outputs to each of the plurality of control apparatus. A program device is coupled to the microprocessor signal input such that data can be entered for the control of each of the plurality of control signal outputs and a timing apparatus is likewise coupled to one of the plurality of signal inputs in a manner to allow the microprocessor to calculate the time of day such that data entered by the program device will selectively control the function of each of the control apparatus as necessary to maintain the environment within the limits set by the operator.
