It was mentioned before that acidification is being done gradually, well..today it was my turn to join one of those steps!. First Frederic saturated the big water tank up to a million ppm CO2. Then we filled the “little” 20 litter bottles and put them in the boat together with the “spider” that looked more like a fine shower, few things more …and ready!
It was a windy morning so the platforms were moving a bit, we placed all bottles on them and after a little struggling we managed to arrive to the mesocosms. We pumped 40 litters in one and 60 litters in another. We even got a few time to chill out while pumping ;)And on the way back: frijoles! beans! were waiting for us.
