PH-testing of the water and discussion on water heating

Aquaponics Group Meeting #7

8 mei 2012

The Aquaponics Group will meet at the Van Gendthallen to talk about how to extract the heat from the LED-lighting, and how to build a system that uses that heat to heat the water in our aquarium. We will also test the PH-values of the water we are using right now, and we'll make a shopping list for the upcoming building weekend. Feel free to stop by. "Pompoen met Speck" will cook us a nice meal, so if you want to have a bite to eat, RSVP on this page.
