Day 8 RET summer Training

Day 8

Today has been an extension of yesterday's progress with setting up our ebb and flow. A new design was constructed by Fern and Sharron (see below). We finally got the flow timed just right!! Great job ladies! Towards the end of yesterday's workday we decided to add an overflow bulkhead to fish tank (1st level) to help drain water to reservoir and keep the pump constantly working. Now we could have just replaced our reservoir with a larger container but this didn't cross our mind. This morning we decided we would also purchase a larger reservoir to prevent tank from overflowing. The link below shows you how to build an ebb and flow.

I spent the morning calibrating our spark probe which if you remember will give us baseline water condition data and which we will use to compare the accuracy of our sensor cluster. I then took readings for both tap water and our aquariums.



I've included a chart of an ideal tank water condition.

                                                      All systems working beautifully!!

                                                          Sump

                                                          We have fish in there somewhere:)
                                                              Tomatoes
                                                              Ebb and flow (similar system as before but taller pvc for ebb)



                                                            atlas sensor
                                                                  Digital reading
                                                        3 sensor probes integrated with arduino
                                                            pH buffers to calibrate sensors
                                                                   Tap water testing


We spent the second part of the day in the library continuing with our research. We started our introduction, added 10 references, and began writing over creating a classroom table aquaponics.
