 +FEEDER:
 +
 +Our first idea was to create a (feeder) to feed the fish. The construction of the feeder was this: it was a plexi- glaas box, which had a spindle at the bottom. The food fell directly to the spindle because of the slope we had designed in the bottom of the box (picture…). The screw was inside a PVC pipe open at the top. The spindle protruding from the box so that the food fell into the tank, so now the pipe was open at the bottom (picture…). The operation was: we introduced the food at the top of the box, the food fell directly to the worm. A motor turned the splindle until the food fell into the tank.

 +TO INCLUDE THIS IDEA IN 8.2

 +another improvement we wanted to include was a feeder and control fish food. We explain the idea in the point... but this idea was not included because it exceeded our budget

 +8.2
 +¿¿¿As we have said due to lack of time and money in the budget, we did not include features that are important for the development of our aquaponic system. Water quality is very important for fish health.???
 +
 +Water quality is very important for fish health. The control of the water is based on temperature, pH and dissolved oxygen. Our aquaponic system controls the temperature so in the future development of our  aquaponic system  it would be necessary to control the pH and dissolved oxygen. The pH is involved in the process of nitrification (conversion of fish waste in a less toxic and compound acceptable to plants), it is essential in the availability of plant nutrients (manganese, copper, zinc and boron) and must be appropriate to the species of fish that wants to grow. Dissolved oxygen has to be suitable (above 3 mg / L) for a good nitrification.
